LF

MV SF6 Circuit Breakers up to 17.5 kV

A compact design for a range especially well suitable for applications sensitive to over voltages, like capacitors banks or inductive loads such as motors.

LF
  • Features

    Range of circuit-breakers up to 17.5 kV:

    • Fixed or withdrawable switchgear with front operating mechanism.
    • 3 poles integrated in a "sealed pressure system" type insulating enclosure, filled with SF6 and equipped with a pressure switch.
    • Stored energy electrical operating mechanism for remote opening and closing of the circuit-breaker.
    • Nominal current from 630 to 5000 A.
    • Short-circuit current from 25 to 50 kA.

    Option:
    • Supporting frame equipped with rollers and ground fixing brackets for a fixed installation.
    • Keylock for locking the circuit-breaker in open position.
    • 42-pin Harting type LV connector.
