Product Details

Indoor side-mounted High Voltage Vacuum Circuit Breaker

ZN63-12 Type side mounted type vacuum circuit breaker is indoor high voltage switch equipment is applicable to rated voltage 12 kV, frequency 50Hz three-phase power system, as the protection and control of electrical use, due to the special advantages of vacuum circuit breakers, especially for applications that require frequent operation rated current, or multiple short-circuit breaking current place.

VS1-12 Type side mounted type vacuum circuit breaker adopts fixed installation, mainly for fixed switch, the circuit breaker can be used alone, but also for ring network power supply, box variant or non-standard power supply system.
