The coil is 440 V AC. It also carries AC-3e and AC-1 utilisation categories, so it covers the energy-efficient motor curve and resistive heating loads as well. Mounts on plate or DIN rail, so it fits a standard panel layout. The IP2X finger protection means the contactor body prevents accidental contact with live parts inside the enclosure — standard for panel-mounted gear. Ambient temperature range is -20 to 70 °C at the coil, with storage down to -60 °C and operation from -5 to 55 °C.
AC-3 is the duty for starting and stopping a squirrel-cage motor — the contactor must handle the locked-rotor inrush (typically 6-8x FLA) during starting and interrupt the running current. If your motor's full-load amps at 440 V are under 120 A, this contactor is electrically sized for it. The AC-1 rating (resistive load) would be higher, but the evidence does not give that figure separately; the AC-3 number is the binding one for motor duty. The mechanical robustness figures (1.5 Gn vibration open, 3 Gn closed; 6 Gn shock open, 7 Gn closed) tell you it holds up on a machine frame or in a mobile installation, not just a stationary panel. Dimensions are 158 mm high, 120 mm wide, 132 mm deep. That depth is the panel depth behind the mounting surface — relevant for enclosure sizing and gland plate clearance.
