Chint NA1 Air Circuit Breaker - NA1 series air circuit breakers are suitable for AC 50Hz / 60Hz circuits with 400V, 690V service voltages and rated service currents up to 6300A. It is mainly used to distribute electrical energy and protect electrical circuits and equipment from overload, low voltage, short circuit fault and single-phase earthing.
With intelligent and selective protection function, the breaker can increase the reliability of the power supply, and avoid unnecessary power failure. The breaker is applicable to power plants, factories, mines (for 690V) and modern high-rise buildings, especially for smart building distribution systems.
Standard: IEC / EN 60947-2.
