24kV Vakuum-Leistungsschalter

1. General TZN-24 series of indoor HV vacuum circuit breakers are used in the switchgear rated 24 kV, 50(60)Hz. They are suitable for making different types of loads and frequent operation, to protect and control the electric equipment in industrial & mining enterprises, power plants and substations, especially suitable for breaking important loads.TZN-24 indoor AC high-voltage vacuum circuit breaker is a vacuum-insulation switching component. The electric conduction part can be made with embedded poles or insulation canisters.Its mechanical lifespan can achieve the class-M2 circuit breaker, i.e. maintenance free for 10,000 times. The mechanical lifespan is up to 20,000 times (60,000 times, with permanent-magnetic device).Small size, simple structure, highly reliability, modular design and excellent technics2.
