Indoor Vacuum and SF6 Circuit Breakers

SF

MV SF6 Circuit Breakers up to 40.5 kV

An optimized design offering a large choice of lateral and frontal mechanism arrangements, especially well suitable for applications sensitives to over voltages, like capacitors banks or inductive loads such as motors and reactors.

SF

  • Features

    Range of circuit-breakers up to 40.5 kV:
    • Fixed switchgear, left or right MV connection, side or front operating mechanism.
    • 3 mechanically linked separate poles, built into a "sealed pressure system" type insulating enclosure containing low pressure SF6 gas.
    • Manual stored energy operating mechanism.
    • Nominal current from 400 to 3150 A.
    • Short-circuit current from 12.5 to 40 kA.
    • SFset: circuit-breaker with self-contained protection chain incorporating a VIP control unit operating without auxiliary supply source
    Option:
    • Electrical operating mechanism.
    • Supporting frame equipped with rollers and ground fixing brackets for a fixed installation.
    • Keylock for locking the circuit-breaker in open position.
    • Pressure switch.
    • 42-pin Harting type LV connector.
