Meba DC Non Polarity Circuit Breakers
DC miniature circuit-breakers for DC. Operation (hereafter short for circuit-breaker) comply with GB 14048.2 Low-voltage switchgear and controlgear— Part2: Circuit-breakers. The circuit-breaker with rated voltage up to 1000V has the feature with small size, high breaking capacity, short flashover and fast closing.
Adopting special arc extinction and current-limiting system, the circuit-breaker could break fault current in DC distribution system quickly and protect PV module which is the important component in solar PV generation system from high DC inverse current and AC feedback current coming from the failure of inverter. So that the reliable service of solar PV generation system can be guaranteed.
