summary

     siemens vacuum circuit breaker             circuit breaker mccb

ZN85-40.5  indoor ac high voltage vacuum circuit breaker (hereinafter referred to as the "circuit breaker") applied to ac 50 hz, 35 kv power System for industrial and mining enterprises, power plants and substations as protection and control equipment, and is suitable for frequent operation. This product performance meet the national standard GB1984 ac high voltage circuit breaker and JB3855 < 3.6-3.6 kV indoor ac high voltage vacuum circuit breaker ", etc. The provisions of the standard.

 

product feature

 

1.circuit breaker adopts integration and modular design, the overall simple and reasonable structure, adopt the up and down, the arc extinguish chamber part above, interlock and operation section below. Use a dedicated gas spring operating mechanism, without adjusting, action is stable and reliable.

 

2. circuit breaker of the three-phase electric circuit of vacuum arcing chamber arrangement within the sealed insulation tube, its insulation tube with reliable electrical and mechanical performance of materials and the vacuum pouring process of mature. Has obviously improved the alternate insulation not only so, but make each phase loop is not affected by outside bad environment, can prevent dust and foreign bodies from entering the main loop, and reduce the overall size of the circuit breaker.

 

3 .circuit breaker adopts Cutler Hammer - companies in the United States production of WL - 35855 - x type vacuum arcing chamber or coil using the latest domestic design vacuum arcing chamber longitudinal magnetic field structure. It adopts ceramic case, presenting and chrome contactor material, small dimension, high insulation level, strong arcing ability, life long and of good open and close short circuit current performance.
