Circuit breaker classified into residual current circuit breaker and molded case. Circuit breaker has small volume, light weight, suitable for frequent operation, arcing without maintenance, the advantages of wide use in power distribution system.
Residual current circuit breaker features:
(1) arc time is short, and has nothing to do with the switch current size, usually only half cycle.
(2) the contactor from small, 10 kv vacuum circuit breaker contact only from about 10mm, long life of circuit breaker.
(3) after the arc contact gap medium fast recovery and split off area near fault performance is better.
(4) due to unclog the wear is smaller when the breaking current, open circuit for 30 to 50 times full capacity, rated current open circuit above 5000 times, the noise is small suitable for frequent operation.
(5) applies to open circuit of capacitive load current.
(6) Small volume, light weight.
