Vacuum Circuit Breaker Miniature vacuum interrupter; Manual, automatic, spring operating mechanism;

Vacuum Circuit Breaker

ZW43-12 outdoor AC high voltage vacuum circuit breaker is mainly used to break and close load current, over-load current and short-circuit current in outdoor 12kV three-phase alternating current 50Hz power system, also suitable for occasion with frequent operations.

The product suitable for substations, industrial and mining establishments, rural power network and occasions with frequent operation to protect and control.

Miniature vacuum interrupter — supreme security — screen exposure, small volume; — long working life-span; — epoxy resin encapsulation  Manual,electric closing,opening mechanism— electric energy storage, electric closing & opening, manual energy storage, manual closing & opening. Clear energy storage stop mark outside, as well as closing & opening estate position. Switch crust— good causticity durability: adopt molding pressure foundry aluminum alloy. — stainless steel switch crust exploited up to now.  Manual,electric closing,opening mechanism— electric energy storage, electric closing & opening, manual energy storage, manual closing& opening. Clear energy storage stop mark outside, as well as closing& opening estate position. Epoxy resin encapsulation — according with the requirement of the environment protection:    no oil or SF6 gas; — confirmed outdoor performance; — durable of ozone and ultraviolet radiation; — be prone to transportation: firm,light,not brittle  Spring mechanism — improvement of the 20A mechanism. More miniature,credible performance, mechanism life reaching twenty thousand times.
