Introduction
ZN*****0.5Permanent Magnetic High Voltage Indoor Vacuum Circuit Breaker is one of Permanent Magnetic Products Series developed and manufactured by Jilin Yongda Group itself, and currently it is the sole permanent magnetic circuit breaker, of which rated voltage can reach *0.5KV domestically.

Features:
1) We use permanent magnetic material in operation device instead of traditional
Device using motor, spring, gears and so forth, which is the main reason for
Achieving such a long using life
2) Our breaker is suitable for steel industry, power plant and electric transformer
Substation, especially for the frequent operation conditions
3) The product is in accordance with the standards of GB******9, IEC*6
4) Compared with electromagnetic operation device, it can get rid of mechanical lock
Catch, save *0% parts in operation device, and achieve repairing-free result
5) Convenient, safe and reliable for operating with the function of manually switch
On/off
6) With moveable and fixed types
7) Vacuum arc-chute is optional, and meets the requirements of customers effectively
8) With the predominant ratio of performance to price
9) No explosion, no pollution, low noise, small volume, long life, repairing-free and less
Maintenance
