Vacuum circuit breaker TANK1

ground faultAClow-voltage

Intelligent Universal vacuum circuit breaker is suitable for AC 50Hz, rated voltage of 400V, 690V, rated current of 630A to 2000A power distribution network. It can avoid overload under voltage, short circuit, single-phase ground fault hazards for distribution of power, the protection of power lines and equipment. The circuit breaker contacts maintenance, overload capability, and strong interrupter breaking ability, can achieve true zero arcing. The circuit breaker suitable environment the ability to highlight and strengthen the design ambient temperature up to -40 ℃, altitude of over 2000 meters above the environment. Especially suitable for workplace air circuit breakers should not be used, such as electrical equipment using wind power, coal, chemical, metallurgical and other explosive industries, suitable for high security residential area distribution.
