Description
MS325-0.4 Manual Motor Starter
The MS325-0.4 manual motor starter is a 5.4 cm width device with a rated operational current of Ie = 0.4 A. This device is used to manually switch on and off motors and to protect them reliably and without the need for a fuse from short-circuits, overload and phase failures.
The manual motor starter offers a rated service short-circuit breaking capacity Ics = 100 kA at 400 VAC and has a trip class of 10A. It features a built-in disconnect function, temperature compensation, trip-free mechanism, and a rotary handle with clear switch position indication.
The manual motor starter is suitable for three- and single-phase applications. Accessories available include auxiliary contacts, signalling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks, and locking devices for protection against unauthorized changes.
Key specifications include width 5.4 cm, height 8.75 cm, depth 7.55 cm, and weight 0.28 kg.
