H. V current-limiting fuses type A/B is mainly used in AC50Hz,
rated voltage 3.6~40.5KV, rated current up to 160A circuit for
protection transformers and power equipments from overload and
short-circuit. It can also be used with load switch, vacuum
It conforms to IEC282-1, GB15166.2 and BS standard.
A/B type H. V HRC current-limiting fuses is bus-bar installation.
The striker parallels to the fuse element made from pure silver.
They are sealed in the fuse tube filled with chemically treated
high-purity quartz sand. The fuse tube is made from heat
resistance, high duty ceramic or expoxy glass.
When fault circuit happens, the fuse link melts, the high-resistant
metal wire paralleling to fuse links melts immediately at the
appearance of the arc, and the striker jumps out to push the
chained equipment contact, signaling the melting automatically
cuttig the circuit.
The striker has spring type striker jumps out to push ethe chained
equipment contact, signaling the melting automatically cutting the
circuit. The striker has spring type striker use high pressure
caused by the lighting powder to push the striker.
