main feature:

 

The operating mechanism adopts the spring operating mechanism specially designed for this circuit breaker. Its structure is simple and reasonable, and maintenance-free for 10,000 operations.

 

The screw propulsion mechanism is adopted, which is labor-saving, stable and has good self-locking performance.

 

Small size, flexible operation, reliable electrical performance, long service life, convenient maintenance and less maintenance.

 

The installation form of ZN85 vacuum circuit breaker in the switch cabinet can be either fixed or handcart type, with good interchangeability.

 

This series of handcart circuit breakers are mainly equipped with 1400mm KYN61 floor cabinets, and fixed circuit breakers are equipped with XGN-40.5, GG1A-40.5 and box-type substations.
