Vacuum circuit breaker model and function

Introduction: The circuit breaker is essentially a kind of current switching device. Its function is mainly to be able to close, load and break the current under the normal circuit conditions and can close, carry and break the abnormal circuit within the specified time.

Vacuum circuit breaker model and function

Vacuum circuit breaker is a kind of circuit breaker developed and improved, because its arc extinguishing medium and the insulating medium after the arc extinguishing contact gap are all named after high vacuum. The vacuum circuit breaker has the advantages of small size, light weight, being suitable for frequent operation and arc extinguishing without maintenance, so that the current application in the distribution network is more popular.

The common models are: ZN63 and ZN63A are industry standard models, VD4 and VS1 are manufacturer-specific models. Both VS1 and VD4 are circuit breakers that can be used in mid-sized handcart cabinets. The main differences are: VS1 adopts tension spring energy storage mechanism, VD4 uses coil spring energy storage mechanism; In addition, VS1 is a domestic product, and there are several companies' product quality. It is also very good. When choosing, you can also consider choosing a domestic brand.
