Description

ZN12 40.5KV 2000A Three-phase AC indoor high-voltage vacuum circuit breaker

overview of indoor high voltage vacuum circuit breaker

ZN12 series of indoor high voltage vacuum circuit breaker is with rated voltage of 40.5kV,three-three phase A.C.50(60) Hz indoor high voltage switch equipment. Clich here for more types of this item.

T he structure of this kind of circuit breaker is simple but with strong breaking capability.It  is suitable for application in the mining industry,substations and power transmission and distribution systems for controlling and protecting the switch.

Especially suitable foe the industry which requires frequently operations like metallurgy fields,electric arc steel plant to control and protect the equipment.

This kind of vacuum circuit breaker can be assembled with truck which can be suitable for many kinds of switchgear such as JYN1,GBC etc

Our products are widely used in:

1 – Transformers and distribution substations
2 – Generator control and protection
3 – Capacitor bank control and protection, etc
