EPB-63M-DC Series Circuit Breaker

• 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.
