NA1 Air Circuit Breaker
1.1 Application scope
NA1 series air circuit breaker is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current up to 6300A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single-phase earthing fault.
With intelligentized and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines (for 690V) and modern high-buildings, especially for the distribution system of intelligentized building.
1.2 Standard: IEC/EN 60947-2.

NA8G Air Circuit Breaker
1.1 Application scope
With rated current from 200A to 6300A, and rated service voltage of AC 415V or 690V, NA8G series air circuit breaker is mainly used in the distribution network with the circuit of AC 50HZ/60HZ to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short- circuit, single-phase earthing fault.
Having art-oriented appearance, high breaking capacity, zero arcover and varities of intellectualized protection functions, the breaker can be used for selective protection with accurate action, no unnecessary power cut, and better power supply reliability.
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.
