Product Description
35kv 36kv Outdoor High Voltage Vacuum Circuit Breaker with Permanent Magnet Drive for Medium-Voltage Overhead Lines
The ZW32-40.5F(M) outdoor high voltage intelligent (permanent magnet) vacuum circuit breaker features an integrated solid sealed pole, current transformer, operating mechanism, and steel box body. Optional isolation switch available. Designed with miniaturization in mind, this breaker uses high-quality steel construction with customizable current transformers to meet user requirements.
Primarily used in medium-voltage overhead line power grids for branching and dosing load current, overload current, and short-circuit current protection.
