1. Product Introduction:
With a rated current from 200A to 6300A, and rated operational voltage 415V 690V, 50Hz, the NA8G series air circuit breaker (hereinafter referred to as "breaker") is mainly used in the distribution network to distribute electric energy and protect lines and power equipment from being damaged by overload, under voltage, short circuit, single-phase grounding and other failures.
Having art-oriented appearance, high breaking capacity, zero arcover and vanities of intellectualized protection functions, that breaker can be used for selective protection with accurate action, no unnecessary power cut, and better power supply reliability.
The product allows the wire to enter or enter from the lower port, and the open frame (draw-out) circuit breaker has isolation function.
That breaker can be widely used for power stations, factories, mines and modern tall buildings, especially the distribution system in the intelligent building, and also widely used in green projects such as wind and solar power generation.
This product meets the requirements in IEC/EN 60947-2
