Indoor high-voltage vacuum circuit breakerDetailed product description：

ZN40-12/630~1250-31.5, ZN41-12/1600~4000-40/50 vacuum circuit breakers are indoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. The structure of this circuit breaker is a frame structure. The circuit breaker can be equipped with CD10 electromagnetic operating mechanism or CT8 spring operating mechanism. It can be used as the preferred circuit breaker for switchgear such as GG1A (F2) and XGN2-12.

The ZN40-12 and ZN41-12 indoor high-voltage vacuum circuit breakers have a simple structure, strong breaking capacity, long service life, complete operating functions, no explosion hazard, and easy maintenance. They are suitable for use as control or protection switches in power plants, substations, and other transmission and distribution systems, especially for breaking important loads and frequent operations.
