ZN63(VS1)-12 Indoor High-Voltage Vacuum Circuit Breaker

Features

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.

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.
