Medium Voltage Vacuum Circuit Breaker

Product Detailed

The vacuum circuit breakers use vacuum interrupters embedded in resin poles Features: 1) The vacuum circuit breakers use vacuum interrupters embedded in resin poles 2) Embedding the interrupter in resin makes the circuit-breaker poles particularly sturdy and protects the interrupter against shocks, accumulation of dust and humidity 3) The vacuum interrupter houses the contacts and makes up the interrupting chamber 4) It serves as an indoor device and operates under the condition of rated 12/17.5KV three phase AC voltage and 50/60Hz frequency 5) It can control and protect electric devices of the industry and mine enterprises, generators and transformer sub-station, is a perfect product for frequent operating condition Specifications: 1) Rated voltage: 12/17.5kV 2) Rated current: 630, 1250, 1600, 2000, 2500, 3150A 3) Rated short circuit breaking current: 25, 31.5, 40KA 4) Mechanical life: 30,000, 20,000, 10,000 times
