It is rated 15 kW at AC-2 duty at 400 V, which covers standard slip-ring motor applications, and 15.5 A at AC-4 at 400 V for reversing or inching duty where the contactor makes and breaks stalled-rotor current. The 55 mm width and 112 mm height fit the standard S2 footprint on a 35 mm DIN rail per DIN EN 50022, with screw and snap-on mounting.
AC-4 at 400 V: 15.5 A — this is the full-load current for reversing and plugging duty; if your application cycles the contactor under load at standstill, this is the number that keeps the arc chute from overheating. The contactor is rated for 1 000 operations per hour at AC-3, 750 at AC-2, and 250 at AC-4 — the mechanical life is 10 million cycles typical, but the electrical life depends on which duty class you run. Wire termination: the main circuit uses screw-type terminals accepting 2x 0.75–25 mm² stranded or 2x 0.5–4 mm² solid. That covers most panel wiring up to 16 mm² at 40 °C ambient.
