NA8 ACB

With a rated current from 200A to 6300A and a rated operational voltage of AC 400V or 690V (specifications 3200 and 6300 AC 690V in trial production), the NA8 series air circuit breaker(hereinafter referred to as circuit breaker) and is mainly used in distribution networks with an AC frequency of 50Hz to distribute electric energy and protect lines and power equipment from being damaged by overload, under voltage, short cirucit, single-phase
grounding and other failures. Having art-oriented appearance, high breaking capacity, zero arcover and a variety of intellectualized protection functions, the circuit breaker can be used for selective protection with accurate action, no unnecessary power cut, and better power supply reliability.
