SIRIUS S0 coupling contactor — 24 VDC coil, 22 A at 600 V
The S0 frame size (85 mm height, 45 mm width, 107 mm depth) keeps panel density manageable.
The 22 A at 600 V and 21 A at 480 V ratings define the maximum continuous current the main contacts can carry at those voltages — useful for resistive or motor loads within those limits. For DC switching, the contactor is rated at 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 2 A at 500 V (–). The 3 hp rating at 230 V gives a quick motor-size reference for North American 230 V single-phase or three-phase applications. Mechanical life is typical 10 million cycles, with maximum switching frequencies of 1000 cycles/h at AC-1, 750 cycles/h at AC-2 and AC-3, and 250 cycles/h at AC-4 (–). The coil connection uses a ring cable lug — plan for that termination style when wiring the control circuit.
No auxiliary switch is built in — if you need auxiliary contacts, plan for a separate add-on block.
