Description
ZN-85-40.5 handcart (Draw out) type with Modular mechanism indoor vacuum circuit breaker is suitable for indoor high voltage switchgear with rated voltage of 40.5kV and three-phase AC 50Hz. It can be used as industrial and mining enterprises, power plants and substations as load current, overload current and short circuit. For current use, it is suitable for frequent operation.
This VCB and operating mechanism used on the layout structure , effectively reduce the depth, mechanism design of circuit breakers is simple, the output curve and the performance is more suitable for the characteristics and requirements of 40.5KV vacuum circuit breaker.

Environment Condition:
- Ambient temperature:-25℃~+40℃
- Altitude: ≤2000m
- Daily average relative humidity: ≤ 95%
- Monthly average relative humidity: ≤90%
- Earthquake intensity: ≤8 degree
- No fire, explosion hazard, severe vibration, chemical corrosion and serious pollution
