ZW32-12M (D) Outdoor Intelligent High Voltage Vacuum Circuit Breaker
Structural features
The permanent magnet mechanism type consists of four parts: vacuum switch body, monostable permanent magnet operating mechanism, intelligent controller, external voltage transformer (PT) or solar panel. Therefore, it has a wide range of coordination and flexible and convenient action program setting method, with high working reliability and safety. It is a new type of "mechatronics" intelligent high-voltage switchgear with control and protection functions. The electric mechanism type consists of four parts: vacuum switch body, electric operating mechanism, intelligent controller, external voltage transformer (PT) or solar panel. Therefore, it has a wide range of coordination and flexible and convenient action program setting method, with high working reliability and safety. It is a "mechatronics" intelligent high-voltage switchgear with control and protection functions.
