C65-63 Circuit Breaker (6KA MCBs)
Scope of Application
C65-63 6KA Circuit Breaker (also called 6KA Household MCB, similar to CHINT NB1-63) is used for the circuit of AC 50Hz, rated voltage of 110V/230/400V, rated current of 1A, 2A, 3A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 60A, 63A to protect overload and short-circuit, as well as use for normal circumstances of the infrequent circuit conversion, also be used as the isolating switch for cut-off circuit to protect circuit and equipment.
6KA Circuit Breaker (6KA Household MCB) are used for industrial, commercial, high-rise and civilian residential and other places.
Meet the standards: GB10963.1, IEC60898-1.
