DW16 Intelligent Air Circuit Breakers


  • General

    DW16 series intelligent air circuit breakers(hereinafter called circuit breaker) are applied for the network circuit of AC 50Hz, rated voltage 400V or 690V, and rated current 100A 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. The breaker can be used to switch the circuit and start the motor infrequently. Frame current 100A to 630A can also be used in AC 50Hz 400V 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.
    The products confirm with IEC60947-2,GB14048.2.
