●Overviews
VS1-12 Side mounted indoor high voltage vacuum circuit breaker is the indoor high voltage switch equipment, which applicable to 12KV rated voltage, frequency 50 hz in the three-phase power system to protect and control the operator. For the special advantage of vacuum circuit breaker is well applied to frequent operation of rated current or the place of many times the breaking short circuit current . VS1-12 Side mounted indoor high voltage vacuum circuit breaker use the fixed installation, mainly for the fixed type switchgear cabinet, the concentrator can be used alone, it also can be used in the ring network power supply, box-type variable, or a variety of non-standard power supply system.
