CT68 operating mechanism of circuit breaker for electric network  ZN12 - 12, ZN12 - 40.5

Summary

CT68 spring operating mechanism is designed and developed by Mingde Electrical,  

on the base of foreigh advanced technology. 

It can be matched with ZN12-12, ZN12-40.5, ZN12-27.5, ZN68A-12 indoor high voltage vacuum circuit breakers in China,  

also can be used in similar circuit breakers in overseas countries.

Features

This operating mechanism gets features of compact structure, long service life, high breaking capacity,

complete running functions and easy maintenance ,  widely used in electric network, petrochemical industry,

metallurgy industry,  mining industry, etc.

Operating Environment Conditions:

- Altitude: below 4000m

- Environment temperature: -25℃ ~ +40℃

- Daily average relative humidity not over 95%, monthly average relative humidity not over 90%.

- Earthquake intensity: no more than 8 degree.

- The products shall be away from weep, fire and explosion, chemical corrosion and strong viration areas.
