EKM1-63DC Series MCB the rated working voltage of DC circuit breakers specially used in photovoltaic can be as high as DC 1000V. The special arc extinguishing and current limiting system can quickly disconnect the fault current of the DC power distribution system. The photovoltaic module, an important component in solar power system, can avoid damages from high DC reverse current and AC feedback current caused by the inverter failure, ensuring a reliable operation of solar PV system.
