Flexible use in industry and infrastructure

SION vacuum circuit breakers control all standard switching tasks in medium-voltage distribution systems and are suited for installation in all air-insulated medium-voltage switchgear. These compact vacuum circuit breakers are easy to install, and they stand out for their long service life.

Consistent portfolio – for voltage levels up to 24 kV
The extensive SION vacuum circuit breaker portfolio includes a wide variety of pole-center distances and widths across flats in the 7.2 - to 24-kV range, as well as a number of specifications from standard circuit breakers for fixed mounting to complete plug-in modules. Identical compact dimensions and connection dimensions across several voltage levels reduce planning costs and the number of switchgear panel versions. All SION vacuum circuit breakers are highly reliable, and available. They are maintenance-free for up to 10,000 operating cycles.
