Vacuum Circuit-Breaker for Lateral Installation Description General information SION 3AE6 Lateral vacuum circuit-breakers from 12 kV to 24 kV Thanks to a range of equipment options, SION vacuum circuit-breakers can be precisely tailored to your requirements. distances as well as various equipment options for voltage levels from 12 kV to 24 kV. Compact dimensions and wellprotected terminals enable simple integration into commonly used medium-voltage switchgear. High reliability and availability are a matter of course, as are 10000 maintenance-free operating cycles. SION vacuum...

Vacuum Circuit-Breaker for Lateral Installation Description Construction and mode of operation Switching medium Proven and fully developed for more than 40 years, vacuum switching technology is the principal arc-quenching element used in vacuum interrupters. Pole assemblies 1 The pole assemblies consist of vacuum interrupters and pole shells. The vacuum interrupters are air-insulated and freely accessible. The pole assemblies are fixed on the mechanism mounting plate and supported by means of the pole shell (6). The vacuum interrupter (5) is mounted rigidly to the upper interrupter support....

Vacuum Circuit-Breaker for Lateral Installation Description Construction and mode of operation Closing spring charged indication A release is a device which transfers electrical commands from an external source, such as a control room, to the latching mechanism of the vacuum circuit-breaker so that it can be opened or closed. The releases are designed for short-time duty up to 1 minute and are reset internally. The circuit-breakers have a mechanically operated spring charged indicator. The charging status of the closing spring can also be queried electrically by means of an integrated...
