It mounts on 35 mm or 75 mm standard DIN rails via screw and snap-on fastening, so it integrates directly into a standard panel layout without adapters.
At AC-3 duty (standard motor switching), this contactor is rated for 37 kW at 400 V, which means it handles a typical 37 kW induction motor on a 400 V three-phase line — common for pumps, conveyors, and compressors in industrial plants. At AC-4 duty (inching or plugging), it carries 66 A at 400 V, so it supports reversing or jogging applications where the motor sees repeated start-stop cycles. The AC-1 resistive load rating is not directly stated, but the AC-3 and AC-4 figures give you the motor-duty boundaries. The contactor measures 70 mm wide, 146 mm high, and 188 mm deep, so it occupies a standard S3 footprint on the DIN rail. Side-by-side mounting is allowed, which helps when packing multiple contactors in a row without derating — useful for multi-motor control panels. Terminal capacity covers solid conductors from 0.5 mm² up to 4 mm² (in dual configurations) and stranded conductors from 10 mm² to 50 mm², so it accepts both control wiring and main power cables without adapters.
