It mounts on standard 35 mm or 75 mm DIN rail via screw or snap-on fastening, and is rated for side-by-side mounting without derating when the ambient stays within -25 to +60 °C. The key motor ratings: 55 kW at 500 V (AC-3 duty) and 45 kW at 400 V (AC-2 duty). For heavy jogging or inching duty (AC-4), it carries 80 A at 400 V. These numbers define the load it can switch — a 55 kW pump on 500 V, or a 45 kW conveyor on 400 V, with the AC-4 rating covering the high-stress starts and reversals that wear standard contactors faster.
Solid wire capacity: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (10 to 50 mm²). Dimensions: 146 mm high, 70 mm wide, 152 mm deep. The 152 mm depth is the main dimension to check against gland-plate clearance or enclosure depth — it's deeper than a typical S2 contactor, so verify the back-of-panel clearance before committing the layout.
