Vacuum Circuit Breaker "Siemen" SION 3AE5

SION vacuum circuit-breakers control all standard switching duties in medium-voltage distribution systems and industrial networks: from switching of load and short-circuit currents up to coupling of network or busbar sections. They are applicable for operation of, for example, overhead lines, cables, transformers, capacitors, and motors.

The comprehensive range of SION vacuum circuit-breakers offers a wide selection of pole-center distances and vertical distances between terminals as well as various equipment options for the voltage levels from 7.2 kV to 24 kV. They are suitable for installation in all established and new air-insulated medium-voltage switchgear as well as for retrofitting existing switchgear.
