Product Description

Product Description

The  ZN63(VS1)- 12  series  indoor  high-voltage  vacuum  circuit breaker is designed for three-phase AC 50Hz power systems with a rated voltage of 12kV. It serves as an indoor switch device for the protection and control units of power grid equipment and 
industrial and  mining  enterprise  power  equipment. This  circuit  breaker  is suitable for frequent operations at rated working current or locations requiring  multiple  interruptions of short circuit current. 
The circuit breaker adopts  an  integrated design of the operating  mechanism and the circuit breaker body, serving both as a fixed installation unit and  capable  of  being  equipped  with  a  dedicated  propulsion mechanism to form a handcart unit.

Service Condition
