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 vertical distance between terminals 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. Fast, reliable, and efficient SION 3AE5 vacuum circuit breakers are suited for all standard switching applications in medium-voltage power distribution and industrial networks: from switching load and short-circuit currents to connecting network or busbar sections. Retrofitting into existing switchgears is also easy, thanks to the wide variety of distances between pole centers and vertical distance between terminals, as well as an extensive range of mounting accessories. Their compact structure, with minimal depth and width dimensions, helps reduce the variety of panels needed. The wide range of panel versions also makes planning easier. The SION 3AE5 vacuum circuit breakers are available with an optional grounding switch for fixed mounting and plug-in versions.
