VS1 series vacuum circuit breakers are divided into handcart VS1 and fixed VS1 according to different use environments, which are suitable for central cabinets and fixed cabinets, which can meet the different needs of customers in different use fields.
The handcart VS1 has been widely used in a variety of central cabinets, and its reliable interlocking and stable performance make it possible to configure most of the central switchgear. In the case of older cabinets, Eato-n's fixed VS1 can also be used with a dedicated mechanical interlocking mechanism to achieve mechanical interlock* functionality in conjunction with the old cabinet.
The VS1 series vacuum circuit breakers are also available in a variety of current levels to meet the needs of power users.
