The circuit breaker uses three-phase pillar structure, and has characters, such as stable and reliable break performance, no fire and explosion, maintenance, small size, light weight, long life, long life, long life, long life, long life, and ECT risk. The circuit breaker uses a sealing structure, the sealing performance is good, and the performance of moisture-proof and anti-prevention is improved, especially in cold and humid.

The indoor epoxy resin is used, which has high and low temperature, ultraviolet linear and anti-aging characterized by silicon gel as a solid insulation method;

The operating mechanism uses a miniaturized spring operating mechanism, which has the low power, open and closing low energy consumption, the direct transmission mode of the mechanism transmission;

Circuit Breaker Opening and Close Operation You can use manual operation, electric operation, or remote operation, can cooperate with the intelligent controller to achieve power distribution automation, and can also cooperate with the repeat controller to make the auto-repeat segmers or;

The circuit breaker can be equipped with three-phase linkage, and some cutters are cut off significantly, and it has a mistable error and circuit breaker body interlocking device.
