Product Description

Product Description
ZW32-12F type outdoor high voltage vacuum circuit breaker / capacitor switch is rated voltage 13.8kV,(max 15KV)  three-phase AC 50Hz outdoor distribution equipment, which is mainly used for breaking, closing power system load current, overload current, short-circuit current. For substation and industrial and mining enterprises distribution system for the protection and control of the role and place of rural power grids frequent operation.

Model Description



Product technical parameters and external dimensions





Product structure features 
The circuit breaker has small size, light weight, anti-condensation, maintenance-free characteristics, can adapt to poor weather conditions and dirty environments.
The models with permanent magnet operation mechanism operates: since the permanent action energy operating mechanism provided by a permanent magnet, the switch quickly to keep the points off position, a small number of mechanical parts, mechanical transmission chain is short, thus greatly improving the switch reliability and mechanical life.



Product Selection



Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
