DW15 Universal Air Circuit Breaker

Application:

DW15 Series air circuit breakers(here in after called circuit breaker)are rated 100A to 4000A in current(up to 630A for limiting current open circuit)and AC 50HZ 380V in voltage.The breaker is mainly used to distribute electric energy in the power distribution network and to prevent the circuit and power source equipment from overload,undervoltage and short circuit.DW15-200,400 and 630 can also be used in AC50HZ 380V electric network to protect the motor from overload,undervoltage or short circuit,or in 660V or 1140v power distrbution network to offer above protections.Under the normal conditions,the breaker can be used to switch the circuit and start the motor infrequently.With the current limiting characteristics,the current limiting breaker is especially suitable for the network where large short-circuit current is likely to occur.
