1  Summary
VMD***0.5 indoors a.c. high voltage vacuum circuit-breaker (hereafter refers to as circuit breaker) is three phase ac *0HZ, the rated voltage *0.5kV indoors switching gear. The circuit breaker conforms to GB********9 " high voltage Circuit breaker", JB********6 "3.6 - *0.5kV Indoors. high voltage Vacuum circuit-breaker" and the IEC related standard. The circuit breaker may supply the industry and mining enterprise, the power plant and the transformer substation using of as the analysis and synthesis load current, the excess current, the fault current, and is suitable for the frequent operation place.
