Product Description

VCB-12 Indoor type ac 25kv vacuum circuit breaker High Voltage Vacuum Circuit Breaker

 

Intorduction:

It is an indoor switchgear with three-phase AC 50Hz rated voltage of 12KV power system. It is used as protection and control unit for power equipment and industrial and mining enterprises. Applicable to places that require frequent operation at rated operating current, or multiple times to break short-circuit current.

The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, and can be used as a fixed installation unit, or can be equipped with a special propulsion mechanism to form a hand truck unit.

Features: small size, light weight, suitable for frequent operation

Main structure: vacuum interrupter, electromagnetic or spring operating mechanism, bracket and other components.
