More reliable structural design

The ML7-63 series miniature circuit breaker adopts high-precision bimetallic material as the inverse time thermal protection element, with precise protection characteristics; The operating mechanism is a four-bar linkage mechanism with low operating force, high sensitivity, and a secure fit; The instantaneous release electromagnet has fine grading, lightweight moving iron core, small inertia, fast response, high sensitivity, and no jamming phenomenon due to the use of an internal structure, greatly improving the reliability of the whole machine; The moving contact has changed from the conventional beam type to a vertical beam type, increasing stiffness and ensuring the closing force of the contact under hot conditions. The moving contact has a smaller body size and lower inertia, ensuring the speed of movement after the moving contact is disconnected, which is conducive to the rapid transfer of the arc; The circuit breaker adopts a large arc extinguishing chamber, and the arc movement trajectory is connected by a large arc iron arc starting plate, reducing the negative force of arc movement and preventing the arc from stopping halfway. There are many iron grids (13 pieces), and the arc is quickly cut, cooled, and extinguished. The arc nozzle adopts multi-layer mesh iron grids to further cool and extinguish the arc, basically ensuring zero arcing and effectively preventing arc short circuits between the anode and cathode; The two sides of the arc chamber are protected by special organic materials, which generate a large amount of insulation vapor at the high temperature of the arc, further increasing the pressure around the arc root and effectively controlling the direction of the metal vapor jet emitted from the electrode. The gas generated by the insulation also cools the arc column, increasing the arc resistance and voltage, providing strong guarantee for the rapid extinguishing of the arc. The insulation materials on both sides also effectively prevent arc damage to the shell, ensuring the high insulation performance of the product.

The ML7-63 series miniature circuit breaker cleverly sets an RJ threshold for the closing force of the operating handle in products with higher rated current levels (5 O A and above), which can only be operated when
Only when the working force reaches a certain value can the contact be closed, and the contact can be closed at a certain high speed, which relatively eliminates the influence of human factors on the contact closing speed, reduces the electrical wear of the contact during connection, and improves the life and reliability of the circuit breaker. The comprehensive effects of various characteristics of circuit breakers include good current limiting characteristics, extremely short arc time, long service life, and reliable performance.

The ML7-63 series miniature circuit breaker has a clear indication of the contact position status.
Due to the rationality of its structural design, the direction of the power supply inlet can be arbitrarily selected.
The wiring terminal adopts a frame structure, which can securely connect both soft and hard wires. The accessories of the circuit breaker are complete, including auxiliary contacts, alarm contacts, shunt release, undervoltage release, and residual current action protection module, which provides great convenience for intelligent applications.
Working and environmental conditions
The upper limit of the surrounding air temperature shall not exceed+40 ��, the lower limit shall not be lower than -5 ��, and the 24-hour average value shall not exceed+35 ��.

The operating mechanism, contact arc extinguishing system, and tripping mechanism are composed of a special plastic shell with high flame retardancy and strength. Strong impact resistance and lightweight. The components of the circuit breaker operating mechanism are made of high-strength plastic products, which ensure sensitivity and reliability while obtaining the lowest moment of inertia, making the time from the beginning of the short circuit fault to the start of the trip mechanism very short. The trip mechanism consists of two parts: a three metal overload reverse time trip mechanism and a short-circuit instantaneous electromagnetic mechanism. The contact arc extinguishing system adopts a special arc angle and aisle arc extinguishing chamber, and has significant current limiting characteristics. The arc moves from the contact to the arc angle and then to the arc extinguishing chamber within about 1ms, and extinguishes the arc within about 4ms.

1�� Scope of application
The DZ12 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is suitable for AC 50Hz, rated current up to 63A, single-phase 230V and three-phase 400V circuits. It is mainly used for overload and short circuit protection of lighting lines, as well as for infrequent line switching under normal circumstances.
The product complies with GB 10963 and IEC 60898-1 standards.

2�� Model and its meaning

3�� Normal working conditions and installation conditions
1. The upper limit of the surrounding air temperature shall not exceed+40 ��, the lower limit shall not be lower than -5 ��, and the average temperature value over 24 hours shall not exceed+35 ��;
Note 1: For working conditions with a lower limit of -10 �� or -25 ��, users must declare it to the manufacturer when placing an order;
Note 2: For working conditions where the upper limit value exceeds+40 �� or the lower limit value is below -25 ��, the user should consult with the manufacturer.
2. The altitude of the installation site shall not exceed 2000m
3. The relative humidity of the atmosphere should not exceed 50% when the ambient air temperature is+40 ��. Higher relative humidity is allowed at lower temperatures, such as reaching 90% at+20 ��. Appropriate measures should be taken for occasional condensation caused by temperature changes;
4. Pollution level: Level 2;
5. Installation category: Class II and Class III;
6. The external magnetic field of the installation site should not exceed 5 times the geomagnetic field in any direction;
7. Generally installed vertically, with a tolerance of 2 ° in any direction;
8. The installation site should have no significant impact or vibration.
4�� Structural features
1. This circuit breaker consists of a handle, an operating mechanism, a trip device, an arc extinguishing device, and a contact system, all of which are installed in a plastic casing to form a single unit. Due to its ability to quickly open and close during operation, the contact wear is minimal and the lifespan is long.
2. The release device has been adjusted and sealed before leaving the factory, so there is no need to worry about unexpected changes affecting the release characteristics.
3. Two pole and three pole circuit breakers are equipped with interlocking trip devices inside, which will not cause single-phase power failure accidents.
