It mounts on a 35 mm DIN rail per EN 50022, using screw and snap-on mounting, and its 45 mm width fits standard panel layouts. The contactor is rated for AC-2 duty at 5.5 kW at 400 V, meaning it handles slip-ring motor starting and reversing, and also carries an AC-4 rating of 8.5 A at 400 V for plugging and inching of squirrel-cage motors.
The AC-2 rating at 400 V is 5.5 kW — that governs continuous motor switching for wound-rotor or slip-ring motors. The AC-4 rating at 400 V is 8.5 A, which is the figure to check for high-frequency reversing or inching duty where the contactor makes and breaks full load current. For type 2 coordination, the required upstream fuse is a gL/gG 20 A; for type 1 coordination, a 35 A gL/gG fuse is specified.
The contactor is 72 mm deep, 45 mm wide, and 57.5 mm tall, so it occupies one standard 45 mm DIN-rail slot. The operating temperature range is -25 to +60 °C, and pollution degree 3 means it tolerates conductive pollution in industrial environments.
