Product Introduction
NDW1A series universal circuit breakers are suitable for distribution networks with AC 50Hz/60Hz, rated current 200A ~ 6300A, rated insulation voltage 1000V/1250V, rated working voltage AC220V/230V/240V, AC380V/400V/415V, AC440V/480V, AC660V/690V. They are used to distribute electric energy and protect lines and power supply equipment from overload, undervoltage, short circuit, single phase grounding faults, etc, it can also be used as an isolating switch. The circuit breaker has a variety of protection functions. While achieving high-precision selective protection, it can also avoid unnecessary sudden power failure and improve the reliability and safety of the power supply system.
