Product Description
ZN63A VS1 24kV 1250A Indoor Vacuum Circuit Breaker
VS1-12 type indoor high voltage vacuum circuit breaker is designed for three-phase AC 50Hz systems with rated voltage for indoor switchgear 12KV power systems. It serves as protection for power equipment enterprises and functions as both a power equipment condition monitor and control unit. Suitable for frequent operation requirements in rated working current or multiple breaking short circuit current scenarios.
The circuit breaker features an integrated design combining the operating mechanism and breaker body. It can be installed as a fixed unit or equipped with a specialized propelling mechanism to function as a hand cart unit.
Key Advantages
