It is rated for 3 kW at 400 V in AC-2 duty (slip-ring motor starting) and 6.5 A at 400 V in AC-4 duty (plugging/inching). At 690 V it handles 4 kW, and at 24 V the rated operational current is 10 A. It occupies 45 mm of DIN rail width, with a height of 57.5 mm and depth of 72 mm.
For general resistive loads (AC-1), the 24 V rating of 10 A gives a baseline, though the actual AC-1 current will be higher at line voltage. The IP20 rating on the front and terminals means it is touch-safe but not sealed against dust ingress — it belongs inside an enclosure.
Main and auxiliary circuits use screw-type terminals. Wire capacity for the main contacts accepts 2x solid conductors from 0.5 to 1.5 mm², 2x from 0.75 to 2.5 mm², or a single conductor up to 4 mm². AWG equivalents are 2x 20–16, 2x 18–14, or 1x 12 AWG. The auxiliary contacts accept the same wire sizes. For Type 1 coordination (contactor may need replacement after a fault), the fuse can be 35 A gL/gG.
