[Low-voltage fuse]RH-01 thermal fuse

2026-6-16 19:36:01

Purpose:
Coil products (power supplies, transformers, motors, chargers, etc.); Network communication equipment (switches, routers, central office devices, etc.) and various household appliances

Characteristics and working principle:
RH-01 thermal fuse is a small sealed structure, disposable overheat protector. Under normal circumstances, the fuse can maintain the reliable operation of the protected product. When the protected product experiences abnormalities and the temperature continues to rise, exceeding the rated temperature of the fuse, the melt inside the fuse immediately melts, quickly disconnecting the circuit and protecting the product from damage.
Technical specifications:
Rated electrical performance: AC 250V; 1A��2A�� 3A
Disconnecting temperature: 95-145 ° C
Action deviation: -10 ° C
Insulation strength: AC 50HZ 500V (between leads),
AC 50HZ 1500V (between the lead wire and the uncharged shell), no breakdown or flashover for 1 minute

Ordering and usage instructions:
Users must accurately measure the actual temperature of the location where the fuse link is installed after thermal stability based on the characteristics of their product, and determine the operating temperature of the fuse link through matching tests, and then propose the operating temperature value for ordering.
When using soldering or spot welding, it is important to avoid overheating and damaging the temperature fuse

[Low-voltage fuse]RY70-240 series thermal fuses

2026-6-16 19:35:52

The RY70-240 series thermal fuse is an organic compound type thermal protection component. It has the advantages of small size, fast temperature sensing speed, and accurate operating temperature. It is an ideal component for overheat protection of various household appliances and electric heating products.

Rated voltage: 125V, 250V
Rated current: 5A, 10A, 15A

Instructions for Use:
Lead forming
The lead of this fuse is made of copper wire, which is prone to bending. But it should not be bent frequently to avoid damage. During the process of bending the lead wire, no pressure should be applied to the body of the fuse. Prevent damage to the sealing resin of the fuse from affecting its sealing performance. If bending is required, it must be done at the lead part 3mm away from the fuse body.
Mechanical Strength Description
The lead pulling force should not exceed 5KG, and the shell strength should be 10KG. Shell deformation can cause poor contact or failure.
Connection of leads
The lead connection must be firm to avoid overheating caused by virtual connection and premature disconnection of the fuse. When welding a fuse to a circuit, it should be noted that the high heat generated by the welding should be lower than the breaking temperature of the fuse.
Installation position of fuse
The fuse needs to be installed in a suitable position on the equipment to maintain its performance. The ambient temperature where the fuse is located must be 25-50 �� lower than the actual operating temperature
moisture-proof
Thermal fuses should not be used in liquid or toxic gas environments.

[Low-voltage fuse]RX2-1000 Fused alarm

2026-6-16 19:17:51

Purpose:
The RX2-1000 fuse alarm is suitable for use as a fuse signal/alarm in electrical circuits with AC 50Hz and rated voltage up to 1000V.
Structural characteristics:
This series of fuse alarms consists of the following three parts:
1. Fused impact body
2. Micro switch (contacts are normally open and normally closed)
3. Support base for fuse impact body and micro switch

The fuse alarm is generally connected in parallel under the fixing screws of the cover plates at both ends of the fuse link. When the fuse link is blown, the fuse impact body will tightly move, pop out the impact pin, push the micro switch, and send out a signal or automatically switch the circuit. The distance between the two fixed (contact) ends on the base can be adjusted within a certain range to accommodate the parallel (fixed) connection of fuse links at different heights.

RX2-1000 (Fused Impact Body Base)
RZS1-1000 (Fused Impact Body Base)
RX1A-1000 (Fused Impact Body Base)

Purpose and Characteristics:
This series of circuit breakers consists of the following three parts:
1. Fused impact body
2. Micro switch (contacts are normally open and normally closed)
3. Support base for fuse impact body and micro switch
The fuse alarm is generally connected in parallel under the fixing screws of the cover plates at both ends of the fuse link. When the fuse link is blown, the fuse impact body will tightly move, pop out the impact pin, push the micro switch, and send out a signal or automatically switch the circuit. The distance between the two fixed (contact) ends on the base can be adjusted within a certain range to accommodate the parallel (fixed) connection of fuse links of different heights

[Low-voltage fuse]HRG Protective fuse switch

2026-6-16 19:08:29

The HRG protective fuse switch (hereinafter referred to as the switch) is compact in size, novel in structure, and has excellent and reliable performance. The outer shell is made of high-quality engineering plastic with flame retardancy, making the switch more safe. Switches are mainly used for lighting circuits in hotels, apartments, high-rise buildings, stations, workshops, laboratories and other units of industrial and mining enterprises, as well as control circuits for small power equipment and machine tools. They are used for manual and infrequent connection and disconnection of load circuits and small capacity lines for short-circuit protection, and can replace imported products of the same type.

2026-6-16 19:06:20

Scope of application
The RS0 series of fast acting fuses with fillers (hereinafter referred to as fuses) are suitable for AC 50Hz, voltage 750V and below, rated current 30 to 480A, mainly used for short-circuit or overload protection of silicon rectifier components and their complete equipment.

The fuse shall be designed, manufactured, and inspected in accordance with GB13539.1 and its related standards.

Model and its meaning
The meaning of the model symbol and code for the RS0 series square tube quick fuse is as follows:

structural characteristics
A fuse is composed of several parts, including a conductive terminal block, a cover plate, a fuse tube, a melt, an indicator, and a filler.
The conductive terminal block adopts a busbar type, which can be directly fastened to the busbar with screws. It has a silver plating layer on the surface and has the characteristics of small installation volume and reliable contact.
The melting tube is made of high-frequency talc ceramic, which has the advantages of high mechanical strength, good arc and heat resistance, and a white and beautiful appearance.
The molten material is a silver sheet with a silver content of not less than 99.9%, and the fuse will not age and cause misoperation under long-term normal working conditions.
The melt is designed with a "V" deformation cross-section, so the fuse has fast speed.
The filler inside the melting tube is quartz sand, which cools the arc and quickly extinguishes it.
The indicator of the fuse is a red and prominent mechanical signal device, which is reliable in action, clear in indication, and easy to identify the action of the fuse.
Users can also install auxiliary contacts when necessary to emit electrical signals. Auxiliary contacts can use micro switches with a driving force less than 150 grams.
