Product Description

Product Description

    SION vacuum circuit breakers control all switching operations in medium-voltage distribution systems and are suitable for installation in all established and new air-insulated medium-voltage switchgear as well as for retrofitting existing switchgear. They are applicable for operation of, for example, overhead lines, cables,transformers, capacitors and motors. The optional installation accessories enable easy integration into switchgear panels, and, maximally equipped as a module with an earthing switch, form almost the complete circuit breaker compartment inside the switchgear.
    Our comprehensive range of circuit breakers offers a wide selection of pole-centre distances and vertical distances between terminals as well as various equipment options

for voltage levels from 7.2 kV to 24 kV. The withdrawable element, contact arms, contacts and bushings enable easy integration in all customary medium-voltage switchgear

types. Identical dimensions and connection dimensions across several voltage levels reduce planning costs and the variety of panel versions. High reliability and availability are a matter of course, as are 10,000 maintenance-free operating cycles.
