It's rated for AC-3 switching up to 690 V, with a maximum operating rate of 800 operations per hour in AC-3 and 250 in AC-4.
The 800 ops/h in AC-3 is enough for frequent starting; the 250 ops/h in AC-4 covers plugging or inching duty. Auxiliary contacts are rated for PLC-level signals — 17 V, 5 mA minimum switching capability. The coil draws 0.78 W on pickup and 0.42 W holding at DC. IP20 on the front, IP00 at the terminals — so the wiring area needs finger-safe covers if the panel door is open.
Side-by-side mounting is allowed — no derating gap needed for adjacent contactors in the same row. Dimensions: 55 mm wide, 112 mm high, 115 mm deep. The S2 frame is the mid-size in the SIRIUS contactor family — larger than S0, smaller than S3 — so check the panel cutout if you're replacing a different frame size.
