Product Description

ZN12-40.5 model indoor high voltage vacuum circuit breaker used in switchgear

1. Introduction:

ZN12-40.5 type circuit breaker is an indoor device with three-phase AC 50Hzand a rated voltage of 40.5Kv.
The mechanism of this circuit breaker and the arcextinquishing chamber system are designed as an integraled Siemens

3AF type spring operating mechanism, which adopts dual-purpose motors for AC and DC energy storage operation or manual operation.
This product is designed with various distances such as 35mm, 400mm,460mm,etc.
It is more convenient to use with different types of switch cabinets. I can be used in fixed cabinel XN17-40.5or in JYN1-405KY10-40.5 cabinets.
