Product Description

Vacuum Circuit Breaker ZN73M-12 Permanent Magnetic Outdoor MV/HV

ZN73M type indoor high voltage vacuum circuit breaker used for ac 50 Hz, rated voltage of 12 kv threephase ac power system, can open and close of the load current, overload and short circuit current. Suitable forswitching on and off different load and frequent operation of electric power line, used for protection and controlthe electrical faclities in industrial and mining enterprises, power plants and substations. The circuit breaker hashigh reliability, the permanent magnetic operating mechanism components is around 70% less than spring operating mechanism. By using longitudinal magnetic field structure arc extinguish chamber open circuit abiitythe circuit breaker operation is simple and reliable with good breaking capability: Circuit breaker uses insulationtube closed structure, insulation performance is strong , manual break-brake is safe and reliable.Loncmechanical life: life of permanent magnetic actuator upto 100000 times, the whole breaker mechanical life is30000 times, so it is especially suitable for the frequent operaion places.Strong function of the controunit:linteligentize dearee is hiah, has the fault alarm, jump atresia, charging voltage can mediate optional over-current and under-voltage protection function.Circuit breaker has handcart type and fixed type, cancooperate with KYN28A, XGN2, GG - lA switchgears, tt is also convenient for oil-free transformation.
