The 45 mm width and 57.5 mm height let it snap onto a 35 mm DIN rail per EN 50022, with 6 mm side clearance needed for side-by-side mounting.
The AC-3 motor rating is 5.5 kW at both 500 V and 690 V, so it handles standard three-phase induction motors up to that load across common European voltage levels. For resistive or lightly inductive loads (AC-1), the same contactor can switch higher currents — the auxiliary contact alone is rated 10 A at 24 V and 6 A at 230 V. Coil consumption is steady at 3.3 W DC for both pick-up and hold, which simplifies power-supply budgeting in a 24 VDC control circuit. Pick-up voltage is 0.85 times rated (about 20.4 VDC), and drop-out is 1.1 times rated (about 26.4 VDC), so the coil reliably pulls in even if the supply sags slightly, and drops out cleanly when the control signal is removed.
Main-circuit screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded conductors — or 1x 12 AWG. The single NO auxiliary contact is rated for switching at 24 VDC (10 A), 60 VDC (2 A), 110 VDC (1 A), and 220 VDC (0.3 A) — useful for signaling back to a PLC input or a status lamp.
