"The NDW3-2500 universal circuit breaker (hereinafter referred to as circuit breaker) can be applied to the distribution network with the AC 50Hz/60Hz, the rated current of 630A~2500A, the rated insulation voltage of 1000 V, the rated working voltage of AC220V/230V/240V, AC380V/400V/415V, AC440V/AC480V, AC660V/690V 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 realize the highly accurate selective protection to avoid unnecessary power failure, and improve the reliability and security of the power supply system.
