Low Voltage DC 600V Intelligent 630A Universal Low Voltage Circuit Breakers CCC

General of Low Voltage DC 600V Intelligent 630A Universal Low Voltage Circuit Breakers CCC

TANW1 series intelligent universal low voltage circuit breaker (hereafter refer to circuit breaker) is suitable for AC 50Hz, rated voltage 400V, 690V, rated current 630-6300A distribution network (4P circuit breaker is suitable for 3-phase-4-wire or 3-phase-5-wire system). The circuit breaker has intelligent protecting function with precise selectivity such as overload, undervoltage, short-circuit, single phase earthing and so on, so as to protect the circuit and the power equipment against damage. It can improve the reliability of power supply and avoid unnecessary power outage.

The circuit breaker can be of open communication interface to support four ways of electrical basic remote measurement: remote metering, remote signalling, remote regulating and remote control, so as to meet the requirement of the power distribution automation system.

The circuit breaker complies with the demands of the following standards: IEC60947-2 and GB14048.2.
