Scope of application
The rated operating voltage of photovoltaic miniature DC circuit breaker can be up to DC1200V. The circuit breaker adopts special arc extinguishing and current limiting system, which can quickly disconnect the fault current of DC distribution system and protect the photovoltaic module from high DC reverse current and inverter fault. The harm of AC feedback current ensures the reliable operation of the solar photovoltaic system.
