The ZN65A-12/T3150-40 vacuum circuit breaker for generator is a new long-life type product developed by our company based on the latest domestic and foreign technologies. Its rated short circuit breaking current is 40kA.

In the type test of circuit breaker for power distribution, the breaking time at full capacity is up to 50 and the mechanical life reaches 60,000 times. This vacuum circuit breaker has also passed the type test of contact breakers. The DC component of the non-symmetry breaking current is more than 70%.

This vacuum circuit breaker features simple structure, stable and reliable operation, as well as convenient maintenance. It comes with a spring operating mechanism.

This product can not only be used as the ordinary protection device for power plants, substations and other transmission and distribution systems but also be used to control and protect some small generator outlet, steelmaking electric furnace and other equipment. Its performance achieves the highest level among similar domestic products.
