ZN73M-12 high voltage indoor vacuum circuit breaker is appropriate to 12kv, 50Hz three phase alternating current system, applicable for power grid breaking, loading current, overload current and circuit breaking current closing in transformer substation and power system of industrial and mining enterprises, especially for switching different nature of load and frequent operation. Permanent magnetic mechanism makes the component decreased 70% co***red with spring mechanism. Vertical magnetic filed structure vacuum interrupter makes the operation more simple and reliable, breaking ability is good too. Sealed insulate cylinder makes better isolate characteristics. The life ***m of magnetic mechanism reaches to 100,000 times and mechanical life 30,000 times, thus especially appropriate to frequent operation places. Fault alarm, antibounce shutting, adjustable charging voltage and optional overload, undervoltage protection function have all indicate it's intelligence.
This type of VCB can be divide into two types: handcart and fixed type. They can match to KYN28A ,XGN2,GG-IA switchgear also carry out non-oil reform.
