For motor loads, it carries 4 kW at 400 V AC-2 and 8.5 A at 400 V AC-4, covering frequent start-stop and reversing applications.
The AC-4 rating of 8.5 A at 400 V is the one that governs plugging and inching duty — the kind of switching that wears contacts faster than a simple AC-3 start. If your application cycles the motor under load, that's the number to match against your actual running current. Coil holding power sits at 3.3 W DC, which keeps the thermal load on the control transformer low in a multi-contactor panel. The magnet coil's closing and holding power are identical, meaning the DC coil doesn't need a separate economy resistor. With pollution degree 3 and IP20 on the front and terminals, this contactor is built for the inside of a cabinet in a typical industrial environment — not washdown or outdoor exposure. The 6 mm side clearance for side-by-side mounting lets you pack multiple units tight on the rail.
