ABB MS132-20L

The MS132-20L lamp circuit breaker is a compact 45 mm width device with a rated operational current of Ie = 20.0 A. This device is used to manually switch on and off lamp loads (and loads with similar characteristics) and to protect them reliably and without the need for a fuse from short-circuits, overload and phase failures. The lamp circuit breaker offers a rated service short-circuit breaking capacity Ics = 100 kA at 400 VAC. Further features are the build-in disconnect function, temperature compensation, trip-free mechanism and a rotary handle with a clear switch position indication. The lamp circuit breaker is suitable for three- and single-phase applications. The handle is lockable to protect against unauthorized changes. Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks and terminal spacers are available as accessory.
