Its key motor ratings are 22 kW at AC-2 duty on 400 V and 38.2 kW at 690 V — the 690 V figure is the one that matters for 690 V line-fed drives or transformers, while the AC-2 rating governs slip-ring motor switching where starting current is higher than a standard squirrel-cage. It accepts stranded conductors up to 2x 50 mm², and at 40 °C ambient the minimum permissible cable is 50 mm² — meaning you don't need to oversize the lug for thermal headroom. Side-by-side mounting is permitted, which keeps the row width tight when ganging multiple contactors for a multi-motor group.
The S3 frame is a mid-range contactor body — 146 mm high, 70 mm wide, 152 mm deep — sized for motors in the 30–50 kW range depending on voltage and duty. The 690 V rating at 60 °C ambient (148 kW) shows this contactor can handle high-voltage, high-power loads, but the 60 °C derating curve means the terminal capacity drops to 35 mm² minimum at that temperature — so if your panel runs hot, you still land 35 mm² cable without splicing. The front face carries IP20 with the cover or box terminal fitted; the terminal itself is IP00, meaning the wiring compartment needs enclosure protection in washdown areas. Mechanical life is 10,000,000 operations typical, and the maximum switching rate at AC-1 resistive load is 650 cycles per hour. That's a fast mover for a contactor this size — it can keep pace with a cycling load like a compressor or a rapid-index conveyor without wearing out the armature prematurely.
The substance prohibitance date is 05/01/2012, which aligns with RoHS compliance for the European market.
