Indoor high pressure vacuum switch

VS1-12 indoor high pressure vacuum switch introduction

VS1-12 type indoor high voltage vacuum circuit breaker is a three-phase AC 50Hz, rated voltage is 12kV, the indoor switchgear of the power system, as the protection and control unit of power equipment, industrial and mining enterprise power equipment. Suitable for frequent operation at rated operating current, or where multiple short-circuit currents are interrupted.

The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, and can be used as a fixed installation unit or a special propulsion mechanism to form a hand truck unit.
