It carries 2 normally-open and 2 normally-closed instantaneous contacts, rated for 10 A at 24 V AC and 10 A at 230 V AC, with derated curves at higher voltages (4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 3 A at 400 V, 2 A at 500 V, 1 A at 690 V, and 0.5 A at 440 V, 0.26 A at 600 V). The DC coil draws 4 W for both pick-up and hold, so there is no inrush spike to size a power supply around — the supply sees a steady 4 W load the whole time the contactor is energized.
The S00 body measures 45 mm wide by 57.5 mm tall by 73 mm deep — that 73 mm depth is the dimension that sticks out from the DIN rail, so check your enclosure depth clearance before committing the BOM. Screw terminals accept 2 × (0.5 to 1.5 mm²) solid or stranded, 2 × (0.75 to 2.5 mm²), or 2 × 4 mm².
