Field of Application
NDW2 series of universal circuit breaker (hereinafter referred to as circuit breaker) can be applied to the distribution network with AC of 50 Hz /
60 Hz, rated current of 200 A ~ 6300 A, rated insulation voltage of 1000 V, rated operational voltage of AC220V / 230 V / 240 V, AC380V / 400 V /
415 V, AC440V / 480 V, AC660V / 690 V, AC1000V for distribution of electrical energy and protecting circuit and power equipment from overload,
under-voltage, short circuit, single phase grounding and harm of other faults, and can also be used as isolation switch at the same time. The circuit
breaker has multiple protection functions. It can avoid unnecessary sudden power failure while realizing highly accurate selective protection, and
improve the reliability and security of the power supply system.
