Product Description

Product Description
According to the relative standards "GB18802.1 and GB50057", the front return circuit of Surge Protective Device(short for SPD) must be in series connection with overcurrent protector. Since the fuse and circuit breaker can't coordinate and cooperate, it may lead to fire and accident of equipment damaged from lightning stroke when the SPD breaks down or occurs short circuit.
Special Circuit Breaker(short for SCB) is specially designed for SPD. It won't disconnect under high impulse current, and can disconnect quickly when there is power current after SPD breaks down, which can eliminate the associated potential risks.
