OEM High Quality Mcb Magnetic Circuit Breaker Manufacturer – Sofielec 6kA Economic RCCB JVL19-63, pin/fork busbar connection, SEMKO,CB,CE approval, A,AC type – Sofielec Electrical Detail:
Product Description
The circuit breaker is also called a circuit breaker, and its interior is mainly composed of main contacts, reaction springs, hooks, levers, electromagnetic tripping and undervoltage tripping devices. It can protect the circuit from overcurrent, overheating, and undervoltage.
Overcurrent protection
When the load is severely short-circuited and the circuit current is very large, the electromagnetic trip coil generates a strong magnetic field and attracts the armature through the iron core. The armature acts to drive the lever to move up. The two hooks are tripped, relying on the action of the reaction spring. , The dynamic and static contacts are disconnected, thereby cutting off the circuit.
Construction and Feature
Provides protection against earth fault/leakage current and function of isolation
High short-circuit current withstand capacity
Applicable to terminal and pin/fork type busbar connection
Contact position indication
Equipped with finger protected connection terminals
Fire resistant plastic parts endures abnormal heating and strong impact
Automatically disconnect the circuit when earth fault/ leakage current occurs and
exceeds the rated sensitivity.
Independent of power supply and line voltage, and free from external interference,
voltage fluctuation.
