Description

ZN63(VS1)-12 series side installation indoor high voltage vacuum circuit breaker is Indoor high voltage switchgear, Applies to rated voltage 12kV, frequency 50Hz three- phase power system, electrical protection and control as the use of vacuum circuit breaker as a result of the special advantages, in particular the need for frequent operation under the rated current or short-circuit current breaking many places.

ZN63(VS1)-12 series side installation indoor high voltage vacuum circuit breaker using fixed installation, the main switchboard for the fixed, the circuit breaker can be used alone, but also for the ring network power supply, box-type variable, or a variety of non-standard power supply system.
