Its thermal protection adjustment range of 0.4…0.63 A sets the overload trip point for the connected motor — set the dial to the motor's full-load current, not the nameplate service factor. Rated for AC-3 utilisation category, it handles the high inrush of squirrel-cage induction motors during starting.
Rated breaking capacity Iq of 50 kA at 400/415 V and 440 V, per IEC 60947-4-1. Coordination is Type 1, so after a short-circuit the starter may need contact replacement, but the downstream motor and cable remain protected.
Motor power and magnetic trip
Motor power rating reaches 0.18 kW at 400/415 V and 440 V AC, 50/60 Hz. The magnetic tripping current is fixed at 8 A — this is the instantaneous magnetic release that clears short-circuits; it does not adjust with the thermal dial. For a motor drawing 0.4…0.63 A full-load, the 8 A magnetic trip provides a healthy margin against nuisance trips during starting inrush.
Width of 45 mm matches the standard 45 mm per-pole pitch on DIN-rail or panel-mount layouts. Depth of 99.6 mm and height of 176.4 mm — verify clearance inside the enclosure door before wiring, especially if a right-angle gland plate or busbar shroud is present. The non-reversing configuration keeps the contactor block compact; reversing applications need a separate GV2DR variant.
