Designation

DW15 series intelligent air circuit breakers(hereinafter called circuit breaker) are applied for the network circuit of AC 50Hz,rated voltage 1140V,and rated current up to 4000A.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.Frame current below 630A can also be used in AC 50Hz 380 electric network to protect the motor from overload,undervoltage and short circuit.
The breaker can be used to switch the circuit and start the motor infrequently.Framecurrent below 630A can be used to switch the circuit and start the motor infrequently.The products confirm with IEC60947-2,GB14048.2.
