AOND series DC miniature circuit breaker is suitable for overload and short circuit protection in rated voltage DC 250-1000V, rated current up to 125A. The circuit breaker can quickly disconnect the fault current of the DC distribution system, in order to protect the photovoltaic module from the harm of high DC reverse current and AC feedback current caused by the fault of the inverter, and ensure the reliable operation of the solar photovoltaic power generation system.
