Vacuum circuit breakers vcb VS1(ZN63) 12kv /24kv 630a/1250a handart type


Product overview

VS1 (ZN63A) - 12 indoor high voltage vacuum circuit breaker, three-phase ac 50 hz, rated voltage of 12 kv power system of indoor switchgear, as power equipment, industrial and mining enterprises, power protection and control unit. Apply to working in the rated electric demand flow frequent operation, or more open circuit short circuit current.
The circuit breaker operating mechanism and circuit breaker unibody design of ontology. Either as a fixed installation unit, also can equipped with feed mechanism, form a handcart unit.
