Product Description
Timetric 11 KV Indoor Vacuum Circuit Breaker Introduction
The vacuum circuit breaker can be divided into two types: fixed type and car type. The overall structure adopts the form of operating mechanism and arc extinguishing chamber before and after arrangement. The main circuit part is three-phase floor type structure. Therefore, it can especially creepage and reduce the accumulation of dust on the surface of the arc extinguishing chamber. It can not only prevent the vacuum arc extinguishing chamber from being affected by external factors, but also ensure that the voltage effect can show a high resistance state even in the humid heat and serious dirty environment.
