Product Description

ZN12-40.5/1250-25 indoor medium voltage sealed Vacuum Circuit Breaker with maintenance free sealed vacuum pole, can equipped with modular spring assembling actuator and permanent magnetic actuator; has the features of reliable performance, long mechanical life, maintenance free, small mechanical movement, has the advantages of simple structure, good process performance, but also can be applied to all kinds of bad working environment.


Vacuum circuit breaker with a small contact distance, arc time is short, breaking the fault current in contact with the characteristics of minor burns, so the vacuum circuit breaker required for the operation of small energy, fast action. It also has a small size, light weight, maintenance workload is small, to fire, explosion, the advantages of small operation noise.


Vacuum circuit breaker mainly includes three parts: vacuum interrupter, electromagnetic or spring Operating mechanism, bracket and other parts.
