Circuit breaker use three phase pillar structure, and have characters such as stable and reliable breaking performance, no danger of fire and explosion, maintenance free, small volume, light weight and long life time, ect. Circuit breaker use sealing structure, good sealing performance, and helpful for improving moisture-proof and condensation-proof performance, especially in cold and humid areas;
Using indoor epoxy resin which is around by silicone gel as solid insulated method has characters of high and low temperature resistance, ultraviolet resistance and aging resistance;
The operating mechanism adopts miniaturized spring operating mechanism, which has low power of energy storage motor, low energy consumption of opening and closing, direct transmission mode of mechanism transmission, fewer parts and high reliability;
Circuit breaker open and close operation can use manual operation, electric operation or remote control operation, and can cooperate with intelligent controller to realize distribution automation, and can also cooperate with recloser controller to make auto recloser or sectionalizer;
Circuit breaker can be equipped with three-phase linkage disconnector, and there are obvious breaks when disconnector is switched off, and it has mistake-proof interlocking device with circuit breaker body.
