The headline motor-switching rating is 37 kW at 400 V under AC-2 duty — this is the category for slip-ring motors, so the contactor is sized for starting and stopping those loads at that power level. For AC-4 duty (plugging, inching, reversing), the rated operational current is 66 A at 400 V, which governs the thermal stress during frequent reversals. That covers the range from control wiring to motor power tails without needing adapters. Front protection is IP20 with the cover or box terminal fitted; the terminal itself is IP00.
RoHS compliance is documented with a substance prohibition date of May 1, 2012, covering the EU directive scope. No other compliance flags (UL, CSA, CE) are explicitly listed in the spec record, but the SIRIUS series typically carries those marks — verify against your local panel certification requirements.
Dimensions are 146 mm high, 70 mm wide, 152 mm deep — the S3 frame fits a standard 70 mm wide DIN-rail footprint. Mechanical life is typical 10 million operations; the switching frequency varies by duty: up to 1,000 cycles/hour under AC-3, 900 under AC-1, 400 under AC-2, and 300 under AC-4.
