SIRIUS S0 power contactor with 110 VDC coil
Rated for AC-2 duty at 7.5 kW and AC-4 at 15.5 A, both at 400 V — the AC-2 figure covers slip-ring motor starting, while the AC-4 rating governs plugging and inching cycles where the contactor opens under full load.
Side-by-side mounting is permitted with 6 mm spacing at the side, which keeps the 45 mm pitch per unit in a multi-contactor row. The S0 frame measures 85 mm high by 45 mm wide by 101 mm deep — depth matters when the panel backplate has limited clearance to the enclosure door or rear gland plate.
Coordination and short-circuit protection
Auxiliary contact switching capacity
The built-in auxiliary contacts handle 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — all DC resistive loads. For AC loads at 230 V the rating is 6 A, and at 400 V it's 3 A.
