           <description>&lt;P&gt;The JL-8CG rail type inverse time overcurrent relay is divided into inverse time overcurrent relay and timed overcurrent relay, and is currently the latest product on the market. The function is based on the same principle as before, reducing the volume by two-thirds, greatly facilitating customer selection. The new overcurrent relay has a novel style and excellent performance. Easy to use and intuitive. It is actually the most ideal product to replace all overcurrent relays.&lt;BR&gt;Rail type overcurrent relay (hereinafter referred to as relay). It is composed of conventional integrated circuits and digital circuits, and its I-t delay characteristics comply with the national society IEC255-4 standard. At the same time, considering the interchangeability of domestic electromagnetic (GL type) inverse time overcurrent relays, non-standard inverse time characteristic relays can also be provided according to actual system operation requirements. Each relay in this series is equipped with a low overrunning quick disconnect outlet. When combined with other types of relays, it can form different types of protection functions. Therefore, it can be applied to relay protection of various types of power equipment.&lt;BR&gt;At present, the transmission systems with voltage levels below 35kV in China's power system generally use current protection devices with incomplete star connections, and overcurrent protection is mostly used. Among them, overcurrent protection is generally time limited or inverse time limited. Considering the traditional practice of relay protection in China, this relay adopts two-phase current protection, which can be selected with reverse time limit or fixed time limit. Both overcurrent and rapid break of the two phases can be independently set, with overcurrent and rapid break independent tripping outlets and alarm signal output contacts.&lt;BR&gt;working principle&lt;BR&gt;The CT secondary current forms a weak voltage through the converter, and the inverse time starting current is set, filtered, rectified, filtered, and automatically extracts the maximum fault phase current, which is sent to level detection to form an open circuit. The characteristic quantity is inserted into the circuit to form different types of inverse time characteristic curves. The V-F circuit is sent to the timer, and when it is consistent with the set delay, the circuit sends a pulse signal to the amplifier to drive the KF inverse time outlet relay. Quick break setting and automatic extraction of maximum fault phase current to be sent to the integration level detector. After discrimination with the preset level, a pulse signal is sent to the amplifier to drive the KS quick break output relay.&lt;BR&gt;&lt;BR&gt;The JL-8CG rail type inverse time overcurrent relay has the following characteristics:&lt;BR&gt;1. No DC auxiliary power supply;&lt;BR&gt;2. Completely using dial switches for setting, convenient and intuitive;&lt;BR&gt;3. Has strong anti-interference ability;&lt;BR&gt;4. There is no mechanical jamming phenomenon in the original electromagnetic overcurrent relay;&lt;BR&gt;&lt;BR&gt;Main parameters of JL-8CG rail type inverse time overcurrent relay&lt;BR&gt;Product features: All products meet the following technical parameters [except for products with special requirements]&lt;BR&gt;1. Return time: In the method of cutting off the circuit, the relay is powered off, and the return time of the relay is not more than 30mS; except for power-off delay time relays&lt;BR&gt;2. The allowable range of voltage variation for the power supply is 0.8 to 1.1 times the rated voltage, and the power supply circuit can also be wide;&lt;BR&gt;3. Contact capacity: The output contact of the relay can disconnect up to 250V, and the DC inductive load circuit with a time constant of 5 &#177; 0.75mS is 50W; the AC circuit with a voltage not exceeding 250V is 50VA. The relay can be connected for a long time for 5A.&lt;BR&gt;4. Power consumption: not exceeding 5W at rated voltage.&lt;BR&gt;5. Environmental temperature: -10 ⊥~+50 ⊥.&lt;BR&gt;6. The conductive terminals of the dielectric strength relay are connected together to withstand an AC voltage of 2000V (effective value) between exposed non charged metal parts or casings, and tested for 1 minute without insulation breakdown or arcing. 7. The conductive terminals of the insulation resistance relay are connected together, and the insulation resistance between the exposed non-metallic parts and the shell is measured with a megohmmeter with an open circuit voltage of 500V, and the insulation resistance is not greater than 300M 次.&lt;BR&gt;8. The contact points of the electric life relay are connected to a circuit load with a specified capacity, and the electric life is 100000 times.&lt;BR&gt;9. Anti interference performance: Relay interference complies with DL478-92 &quot;General Technical Conditions for Static Relay Protection and Safety Automatic Devices&quot;.&lt;/P&gt;

           <description>&lt;P&gt;The HGL series static inverse time overcurrent relay is used in relay protection circuits of motor transformers and other equipment, as well as transmission and distribution systems. It is particularly suitable for plants without DC equipment. When the main equipment or transmission and distribution system experiences overload and short circuit faults, the relay can reliably operate within the predetermined time limit, cut off the faulty part, and meet the requirements of the power department's compression time step difference countermeasures.&lt;BR&gt;&lt;BR&gt;2. Main technical parameters&lt;BR&gt;Overcurrent setting range: 2-20A, with a step difference of 0.1 A.&lt;BR&gt;Quick break current multiple: 2-12 times.&lt;BR&gt;Delay time setting range: 0.1-999.9S, with a difference of 0.1S.&lt;BR&gt;The setting range of quick break delay time is 0.1-0.9S, with a step difference of 0.1S.&lt;BR&gt;Contact capacity: AC250V, can be connected for a long time for 5A, and the closing contact can break the current AC ≒ 2A.&lt;BR&gt;Power consumption: When the current is at the rated value, the power consumption of the relay is not more than 5W.&lt;BR&gt;&lt;BR&gt;3.

           <description>1. Application scope&lt;BR&gt;The HSL series static inverse time overcurrent relay is applied in the relay protection circuit of motor transformers and other equipment, as well as transmission and distribution systems. It is suitable for plants without DC equipment. When the main equipment or transmission and distribution system experiences overload and short circuit faults, the relay can reliably operate within the predetermined time limit, cut off the faulty part, and meet the requirements of the power department's compression time difference countermeasures.&lt;BR&gt;The HSL series can replace GL-11, 21, 12, 22, 13, 23, 14, 24&lt;BR&gt;15. 25, 16, 26 overcurrent relays can also replace DL-10, DL-&lt;BR&gt;20, DL-30 series current relay.&lt;BR&gt;&lt;BR&gt;2. Main technical parameters&lt;BR&gt;Overcurrent setting range: 2-9.9A, with a step difference of 0.1A.&lt;BR&gt;Quick break current multiple: 2-8 times.&lt;BR&gt;Delay time setting range: 0.1-9.99S, with a difference of 0.1S.&lt;BR&gt;Contact capacity: AC250V, can be connected to 5A for a long time, and the closing contact can break the current AC ≒ 2j&lt;BR&gt;Power consumption: When the current is at the rated value, the power consumption of the relay is not more than 5W.&lt;BR&gt;&lt;BR&gt;3. Terminal wiring and setting methods&lt;BR&gt;-Terminal wiring diagram&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200709/2007925133620230.jpg&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 600px; HEIGHT: 110px&quot; border=0 hspace=0 alt=&quot;Contact diagram of HSL-10 series static timed overcurrent relay&quot; src=&quot;/uploadfiles/200709/2007925133620230.jpg&quot; width=600 height=110&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;-Use wiring diagram&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200709/2007925133641568.jpg&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 600px; HEIGHT: 208px&quot; border=0 hspace=0 alt=&quot;Wiring diagram of HSL-10 series static timed overcurrent relay&quot; src=&quot;/uploadfiles/200709/2007925133641568.jpg&quot; width=600 height=208&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;Setting method&lt;BR&gt;There are three sets of digital switches on the relay panel, from left to right, which are the overcurrent action value, current quick break multiple, and overcurrent action time value. For example, if the overcurrent setting value is 7.5A and the quick disconnect digital switch is set to &quot;3&quot;, the quick disconnect setting value is 22.5A, the maximum overcurrent action time is 9.99s, and the step difference is 0.01S.&lt;BR&gt;</description>

           <description>&lt;P&gt;The GG-22 overload relay is used to protect the AC generator from overload when disconnecting parallel running generators.&lt;BR&gt;&lt;BR&gt;Overview of Structure 2&lt;BR&gt;Overload relays are based on the principle of induction and operate with a rotating magnetic field.&lt;BR&gt;The relay consists of an upper and lower magnetic circuit system in the magnetic conductor. The current coil is placed in the upper magnetic circuit system and is powered by a current transformer connected to a certain phase of the generator. Two series connected voltage coils are placed in the lower magnetic circuit system and connected between the phase voltages of the generator.&lt;BR&gt;The rotating system of the relay has an aluminum disc fastened to the shaft (with steel shaft tips pressed into both ends of the shaft), and the rotating system is supported by steel balls located on the bearing screws through the shaft tips.&lt;BR&gt;A gear is installed on the shaft of the aluminum disc, which meshes with the gear equipped with relay contacts: a balance spring that generates a reaction torque is fastened to the contact gear shaft.&lt;BR&gt;The static contacts of the relay are fixed between the phosphor copper sheets on the rubberwood insulation base, and the screws installed on the contact base can adjust the position of the relay's static contacts. When the protected power grid experiences overload, torque is generated on the aluminum plate; Under the action of aluminum disc torque, the relay contacts close, the automatic switch on the current collection and discharge system operates, the relay current coil circuit is disconnected, and the balance spring of the rotating system returns to its original position.&lt;BR&gt;Changing the number of turns of the relay current coil can alter the setting value of the relay's operating power, and the tap of the current coil is welded to the socket. The socket has three sockets, which correspond to 105%, 110%, and 115% of the rated power of the relay at rated voltage. When using a standard instrument current transformer, the relay operating power should be adjusted according to Table 1.&lt;BR&gt;For the set value of known action power, simply insert it into the corresponding socket.&lt;BR&gt;When converting loads, it is necessary to first screw the spare plug into the socket according to the required operating power, and then unscrew the first plug and insert it into the empty socket.&lt;BR&gt;The relay has a delay device, which is related to power and is generated by the rotation of the aluminum disk of the rotating system between the permanent magnet poles. The permanent magnet is installed at the front of the relay.&lt;BR&gt;Changing the stop position of the relay's moving contact can alter the setting value of the relay's action delay.&lt;BR&gt;The stop lever is pointer type and can move along the dial. The division unit is seconds, and 0.25s, 0.5s, and 1s are engraved on the dial&lt;BR&gt;1.5sㄛ2sㄛ2.5s﹝&lt;BR&gt;When the contact is closed, the steel stopper located on the moving contact is close to the small permanent magnet fixed on the bottom plate of the contact system and is attracted, thereby ensuring the reliable closure of the contact system.&lt;BR&gt;The magnetic conductor, rotating system, and contact system of the relay are installed on an aluminum silicon alloy frame, which is mounted on an aluminum silicon alloy base. The base is equipped with two terminal blocks, which are connected to the coil and contacts of the relay with wires. The base is also used to fasten the relay to the distribution panel.&lt;BR&gt;The relay has a cover to protect the mechanism from mechanical damage and prevent water droplets from entering.&lt;BR&gt;The internal wiring diagram during the relay period is shown in the GG-21 relay.&lt;BR&gt;&lt;BR&gt;3 Technical data&lt;BR&gt;3.1 Rated voltage: 127 and 230V, 50HZ.&lt;BR&gt;3.2 Rated current: 5A.&lt;BR&gt;3.3 When the relay is at its maximum sensitive angle, the operating current is 3.35A (at this time, the power factor of the generator grid is 1)&lt;BR&gt;3.4 Maximum sensitivity angle: 30 &#176; -3 &#176;.&lt;BR&gt;3.5 Action power: 105%, 110%, and 115% of the rated action power.&lt;BR&gt;3.6 The rated operating power is rated voltage &#215; 3.35 &#215; 1.&lt;BR&gt;3.7 Action time at 1.2 times the action current: 0.25s, 0.2s, 1s, 1.5s, 2s, and 2.5s.&lt;BR&gt;The rotational torque of the 3.8 relay is determined by the following equation:&lt;BR&gt;M=K&#183;Vp&#183;Ip&#183;COS(w+汐)&lt;BR&gt;Among them: K-proportionality coefficient VP - voltage applied to the relay&lt;BR&gt;IP - current through relay w - vector VP and phase angle between IP&lt;BR&gt;汐 - For this relay, it is 30 &#176;&lt;BR&gt;The setting of relay action power is carried out when the phase angle between rated voltage and current lead voltage is 30 &#176;.&lt;BR&gt;3.10 Delay setting is carried out when the phase angle of the lead voltage is 30 &#176; at 1.2 times the operating current of the rated voltage.&lt;BR&gt;The ratio of the return power of the 3.11 relay to the operating power when the return coefficient returns to the initial position is not less than 0.6, and it is checked when the operating time is 0.25-1s.&lt;BR&gt;The appearance and opening size diagram of the 3.12 relay are shown in the GG-21 relay.&lt;BR&gt;3.13 Actual data of operating power of GG 22 relay when using standard measurement of current transformer&lt;BR&gt;&lt;BR&gt;

           <description>1 Purpose&lt;BR&gt;This relay is used for overload and short-circuit protection of motors, transformers, and transmission lines, and can also be used for overcurrent protection in AC operating circuits. Suitable for use in protection circuits with specific action time requirements for inverse time limits and definite time limits.&lt;BR&gt;&lt;BR&gt;2. Action principles and structural characteristics&lt;BR&gt;2.1 Action principle&lt;BR&gt;The operating principle of this series of relays is composite, consisting of two components: inductive and electromagnetic, which share a common coil. When the coil of the relay passes through an alternating current, two magnetic fluxes with a certain phase difference are generated in the shielding part of the iron core. As a result of the interaction between these magnetic fluxes and the eddy currents induced in the disk, a torque is generated on the disk. At an operating current of 20-40%, the disk begins to rotate. At this time, the relay does not operate because the fan teeth and worm gear are not engaged.&lt;BR&gt;When the current in the coil increases to the set current, the electromagnetic torque is greater than the reaction torque of the spring, and the frame rotates, causing the fan teeth to mesh with the worm and rise. At this time, the moving iron of GL-21, 22, and 25 overcurrent relays is pushed by the toothed top rod, causing the air gap on the right side of the magnet to decrease and the air gap on the left side to increase. Therefore, the moving iron is attracted by the magnetic conductor, causing the relay contacts to move.&lt;BR&gt;GL-21﹜ The 22, 23, and 24 type relays have a dynamic closing main contact, which can also be modified into a dynamic breaking contact as needed.&lt;BR&gt;GL-25﹜ The 26 type relay has a conversion main contact with a large contact capacity, ensuring that the secondary circuit of the current transformer will not open during the relay operation.&lt;BR&gt;GL-23﹜ In addition to the main contacts mentioned above, the 24 and 26 type relays also have a pair of signal contacts operated by inductive elements, and the main contacts are only controlled by electromagnetic elements.&lt;BR&gt;When the current in the relay coil is less than the instantaneous setting value, the action time limit of the inductive element is inversely proportional to the current. When the current in the input coil reaches a certain multiple of the set current (i.e. instantaneous setting value), the electromagnetic component will act instantaneously. Therefore, the action time limit of the relay has the characteristics of definite time limit and inverse time limit.&lt;BR&gt;2.2 Structural Features&lt;BR&gt;The relay has seven taps to adjust the operating current of the inductive and electromagnetic components. The operating current of electromagnetic components can also be adjusted by changing the air gap between the moving iron and the electromagnet. The relay has a mechanism for adjusting the action time setting value of the sensing element and a main contact action signal board. This signal board can be reset by a mechanism installed on the housing to return after its action.&lt;BR&gt;The components of the relay are mounted on a metal base and covered with a transparent organic glass shell.&lt;BR&gt;The relay is installed on a vertical panel and can be wired in front or behind the board.&lt;BR&gt;The internal wiring diagram of the relay is shown in Figure 1.&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200611/2006113221920721.gif&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 680px; HEIGHT: 100px&quot; border=0 hspace=0 alt=&quot;GL-20 series current relay contact diagram&quot; src=&quot;/uploadfiles/200611/2006113221920721.gif&quot; width=680 height=100&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;Figure 1 Internal wiring diagram of GL-20 series relay (back view)&lt;BR&gt;&lt;BR&gt;3 Technical data&lt;BR&gt;3.1 The rated data and adjustment range of various relays are listed in the following table&lt;BR&gt;&lt;BR&gt;

           <description>&lt;P&gt;Application of JFL-14 Negative Sequence Overcurrent Relay:&lt;BR&gt;&lt;BR&gt;The JFL-14 negative sequence overcurrent relay is used as a backup protection for asymmetric short circuits and negative sequence overload protection.&lt;BR&gt;This relay consists of an integrated circuit that forms a filtering circuit and an execution circuit, with advantages such as high sensitivity, fast speed, and low power consumption. The setting of the relay is carried out using a dial switch on the panel, which is intuitive and convenient. The relay is equipped with two negative sequence current settings, and the small action value range can lock the large action value range, forming a dual configuration.&lt;BR&gt;&lt;BR&gt;Working Principle:&lt;BR&gt;The current measurement circuit consists of a current transformer and a negative sequence current filter, while the phase shifter and adder form the negative sequence current filter. UCK2 is delayed by a phase shifter by 90 and amplified by 2/3 times before being added to UCK1 to form the negative sequence current filter output UCK5.&lt;BR&gt;UCK5=UCK1+(- J) * 2/SQRT (3) * UCK2;&lt;BR&gt;For LH1, choose W34=2W56, which means WA=3WO;&lt;BR&gt;For LH1, choose W34=W56, i.e. WB=WC;&lt;BR&gt;When the zero sequence component is input, IAO=IBO=ICO=IO, while in WO, IAOWA-3IOWO=O is calculated based on the ampere turn principle using 3IO; IBOWB-ICOWC=Oㄛ So the secondary side of current converters LH1 and LH2 does not reflect zero sequence components.&lt;BR&gt;Properly selecting parameters to ensure that when inputting three-phase positive sequence current, UCK5&amp;nbsp;=&amp;nbsp;O﹝&lt;BR&gt;Therefore, when inputting three-phase negative sequence current, UCK5&amp;nbsp;=&amp;nbsp;2UCK1&amp;nbsp;=&amp;nbsp;4&amp;nbsp;3UCK2﹝&lt;BR&gt;The output UCK5 of the negative sequence current filter is compared with the threshold voltage of the level detection after being set to a fixed value, rectified, and filtered.&lt;BR&gt;During normal operation and symmetrical three-phase short circuit, UCK5&amp;nbsp;=&amp;nbsp;0Vㄛ The level detection outputs a positive signal, but the relay does not operate.&lt;BR&gt;When a two-phase short circuit occurs, the fault current reaches UCK6&amp;gt;UCP2, UA47 is a negative signal, and J1 acts; UCK7&amp;gt;UCP4, UA67 is a negative signal, J2 is activated.&lt;/P&gt;

           <description>Purpose:&lt;BR&gt;&lt;BR&gt;JGL-110 series integrated circuit inverse time overcurrent relay (hereinafter referred to as relay). It is composed of conventional integrated circuits and digital circuits, and its I-t delay characteristics comply with the International Electrotechnical Commission IEC255-4 standard. At the same time, considering the interchangeability of domestic electromagnetic (GL type) inverse time overcurrent relays, non-standard inverse time characteristic relays can also be provided according to actual system operation requirements. Each relay in this series is equipped with a low transient over trip outlet. When combined with other types of relays, it can form different types of protection functions. Therefore, it can be applied to relay protection of various types of power equipment.&lt;BR&gt;At present, the transmission and distribution systems with voltage levels below 35kV in China's power system generally adopt current protection with incomplete star connection for protection configuration. Overcurrent protection is mostly used, among which overcurrent protection is generally timed or inverse timed. Considering the traditional practice of relay protection in China, this relay adopts two-phase current protection. Overcurrent protection can be selected with inverse time or definite time, and both overcurrent and quick break of the two phases can be independently set. Overcurrent and quick break have independent tripping outlets and alarm signal output contacts.&lt;BR&gt;&lt;BR&gt;JGL-110 series inverse time overcurrent relay model name:&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200611/2006111184824467.gif&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 454px; HEIGHT: 290px&quot; border=0 hspace=0 alt=&quot;JGL-110 series inverse time overcurrent relay model description and technical parameters&quot; src=&quot;/uploadfiles/200611/2006111184824467.gif&quot; width=454 onload=&quot;javascript:if(this.width&gt;screen.width-500)this.width=screen.width-500&quot; height=290&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;Working Principle:&lt;BR&gt;The CT secondary current forms a weak voltage through the converter, and the inverse time starting current is set, filtered, rectified, filtered, and automatically extracts the maximum fault phase current, which is sent to level detection to form an open circuit. The characteristic quantity is inserted into the circuit to form different types of inverse time characteristic curves. The V-F circuit is sent to the timer, and when it is consistent with the set delay, the circuit sends a pulse signal to the amplifier to drive the KF inverse time outlet relay. Quick break setting and automatic extraction of the maximum fault phase current are sent to the integral level detector. After being judged against the preset level, a pulse signal is sent to the amplifier to drive the KS quick break output relay.&lt;BR&gt;&lt;BR&gt;Usage:&lt;BR&gt;4.1 The time limit characteristics of this relay can meet the requirements of IEC255-4, and can also comply with other types of inverse time limit relays. The A, B, and C types of inverse time limit characteristic curves specified in IEC255-4 are expressed as follows:&lt;BR&gt;&lt;BR&gt;A:t=I*=0.14k/2/I*0.02ㄜ1(s)&lt;BR&gt;B:t=13.5k/2/I*ㄜ1(s)&lt;BR&gt;C:t=80k/2/I*2ㄜ1(s)&lt;BR&gt;G: T=0.236k/2/I * 0.02-1 (s) (replacing GL type relay)&lt;BR&gt;In the formula:&lt;BR&gt;I * - The fault current is the standard value of the starting current&lt;BR&gt;I *=I - actual fault current/IF - starting current setting value&lt;BR&gt;If I * is not greater than 1.2, it is not recommended to use the segment&lt;BR&gt;K: Action time displacement scale k=0.1~9.9DK=0.1&lt;BR&gt;t: Relay action time unit (s)&lt;BR&gt;4.2 Inverse time limit starting current setting The starting current setting value mainly depends on the short-circuit current of the protected equipment. According to the protection range of the fault current, the value of the IF dial switch is changed. According to the panel calculation formula, the setting value IF of the inverse time limit starting current can be obtained.&lt;BR&gt;4.3 Inverse time characteristic time setting Inverse time characteristic time setting is mainly used to cooperate with various levels of inverse time protection, so that the protection can selectively and quickly cut off faults. The time limit requirement can be selected according to the I-t characteristic diagram to select any curve in the curve bundle, and the dial switch value of K value can be turned to indicate one of the curve bundles. When a timed overcurrent protection is required, simply turn the inverse/timed limit function switch to the timed limit position, and the timed limit time will be the value of the K switch.&lt;BR&gt;4.4 In order to cooperate with the inverse time limit outlet and solve the problem that the inverse time limit cannot meet the operating requirements and quickly cut off nearby faults in different states, the value of the dial switch of the instantaneous current setting value IS is multiplied by the value of IF to obtain the instantaneous current setting value of IS.&lt;BR&gt;4.5 This relay is a two-phase or single-phase overcurrent, and the operating currents of the two phases can be set separately.&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200611/2006111184836812.gif&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 401px; HEIGHT: 172px&quot; border=0 hspace=0 alt=&quot;Calculation formula for JGL-110 series inverse time overcurrent relay&quot; src=&quot;/uploadfiles/200611/2006111184836812.gif&quot; width=401 onload=&quot;javascript:if(this.width&gt;screen.width-500)this.width=screen.width-500&quot; height=172&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;Main technical parameters:&lt;BR&gt;5.1 Rated value: AC current IN: 1A, 5A, 10A;&lt;BR&gt;Communication frequency FN: 50Hz, 60Hz;&lt;BR&gt;Auxiliary DC voltage: 48V &#177; 10%, 110V/220V &#177; 20%.&lt;BR&gt;5.2 Inverse time starting current: IF=0.1IN (1-10.9).&lt;BR&gt;That is, when IN=1A, the IF setting range is 0.1A to 1.09A;&lt;BR&gt;When IN=5A, the IF setting range is 0.5A-5.45A;&lt;BR&gt;When IN=10A, the IF setting range is 1A to 10.9A.&lt;BR&gt;5.3 Rapid current: IS=(2-21.8) IF.&lt;BR&gt;That is, when IN=1A, the IS setting range is 0.2A to 23.76A;&lt;BR&gt;When IN=5A, the IS setting range is 1A to 118.8A;&lt;BR&gt;When IN=10A, the IS setting range is 2A to 237.6A.&lt;BR&gt;(Note: Setting current greater than 100A is not recommended) Inverse time delay scale: K=0.1-9.9.&lt;BR&gt;Time limited delay: t=(0.1~9.9) s&lt;BR&gt;5.4 Action time: For inverse time delay, please refer to the appendix.&lt;BR&gt;Rapid action shall not exceed 60ms at 1.2IS;&lt;BR&gt;Under 2IS, it should not exceed 30ms.&lt;BR&gt;The consistency of action time shall not exceed &#177; 5%.&lt;BR&gt;5.5 Error&lt;BR&gt;The current setting value shall not exceed &#177; 5%;&lt;BR&gt;The inverse time setting value shall not exceed &#177; 5% (&#177; 10% when I * is less than 2);&lt;BR&gt;The time limit setting value shall not exceed &#177; 10%+20ms.&lt;BR&gt;5.6 Return time:&lt;BR&gt;The inverse time limit is at 15IF, and the quick action is 60ms at 10IS&lt;BR&gt;5.7 Return coefficient: not less than 0.9.&lt;BR&gt;5.8 Power consumption: not exceeding 0.8VA/phase under AC current loop IS;&lt;BR&gt;Under the DC voltage circuit, the voltage should not exceed 10W.&lt;BR&gt;5.9 The overload capacity of the current circuit can withstand continuous operation under 2IN (IN=1A, 5A);&lt;BR&gt;10s under 10IN;&lt;BR&gt;40IN for 1 second.&lt;BR&gt;5.10 Contact output: main contact overcurrent 2 conversion;&lt;BR&gt;Quick 2 conversion.&lt;BR&gt;Signal contact 1 is open/closed.&lt;BR&gt;5.11 Contact Capacity:&lt;BR&gt;Disconnected: DC 250V/0.5A,=5ms &#177; 0.75ms, with a capacity of 50W;&lt;BR&gt;250V/2A communication, coso=0.4 &#177; 0.1, with a capacity of 250VA.&lt;BR&gt;5.12 Voltage Test: Insulation Test 2kV, 50Hz, 1min between different circuits; 1kV, 50Hz, 1min between contacts of the same group.&lt;BR&gt;5.13 Allowable operating temperature range: -10 ⊥ to+40 ⊥.&lt;BR&gt;5.14 Storage temperature: -25 ⊥ to+75 ⊥.&lt;BR&gt;5.15 Weight: not exceeding 2.2kg.&lt;BR&gt;&lt;BR&gt;Wiring diagram behind the relay:&lt;BR&gt;The contacts in the picture are in a state where the relay is not powered or not functioning&lt;BR&gt;&lt;BR&gt;&lt;A href=&quot;/uploadfiles/200611/2006111184851442.gif&quot; target=_blank&gt;&lt;IMG style=&quot;FILTER: ; WIDTH: 333px; HEIGHT: 204px&quot; border=0 hspace=0 alt=&quot;JGL-110 series inverse time overcurrent relay wiring diagram&quot; src=&quot;/uploadfiles/200611/2006111184851442.gif&quot; width=333 onload=&quot;javascript:if(this.width&gt;screen.width-500)this.width=screen.width-500&quot; height=204&gt;&lt;/A&gt;&lt;BR&gt;&lt;BR&gt;Relay external dimensions and opening dimensions:&lt;BR&gt;Refer to Figures 4 and 8 in the protruding modular insertion structure.&lt;BR&gt;&lt;BR&gt;Ordering instructions:&lt;BR&gt;8.1 Relay name and model.&lt;BR&gt;8.2 Auxiliary DC voltage rating and rated current (if there are special requirements, please specify separately).&lt;BR&gt;8.3 If the contact form is a special requirement, please specify it separately.&lt;BR&gt;8.4 Order quantity.&lt;BR&gt;8.5 ABB structure relay matching: relay base and several sockets (to be ordered separately).&lt;BR&gt;</description>
