CONDITIONS OF USE
CLBW1 series intelligent universal low-voltage circuit breaker (hereinafter
referred to as circuit breaker), suitable for ac 50Hz, rated voltage up to 1000V
and below.In the distribution network with rated current of 400A ~ 6300A, it is
used to distribute electric energy and protect circuit and power equipment from
overload, undervoltage, short circuit, single-phase grounding and other faults.
Circuit breaker with intelligent protection function, selective protection accurate,
can improve the reliability of power supply, avoid unnecessary power failure.At
the same time with open communication interface, can be four remote, to meet
the requirements of the control center and automation system.The circuit breaker
can be used as isolator without intelligent controller and sensor.
