Scope of application
The rated working voltage of MG1-63 small DC circuit breaker can be as high as DC1200V. This circuit breaker adopts a special arc extinguishing and current limiting system, which can quickly disconnect the fault current of the DC distribution system, protect important components in the solar power generation system, and protect the photovoltaic module from the harm of high DC reverse current and AC feedback current caused by inverter faults, ensuring the reliable operation of the solar photovoltaic power generation system.
