It switches 6 A in AC-3/AC-3e duty at ≤440 V — that's the standard motor-starting category for squirrel-cage motors, so it handles inrush and break without welding. The 24 V AC 50 Hz coil keeps it in the common control-voltage range for panel designs. One normally open auxiliary contact is built in for feedback or interlocking.
The utilisation categories tell you what loads it can handle: AC-3 (motor starting) and AC-1 (resistive). For a 6 A motor at 400 V, this contactor is sized for small conveyors, fans, or pumps — not for heavy-duty or high-cycle applications. The AC-3e rating extends the same category with enhanced electrical endurance, which matters if the line cycles frequently. The 24 V AC coil draws from a standard control transformer; verify the 50 Hz frequency matches your supply. Mounts on DIN rail or plate, so it integrates into a standard panel without extra brackets.
Also meets EN/IEC 60335-1 Clause 30.2 and -2-40 Annex JJ for appliance safety, which broadens its acceptance into HVAC and white-goods lines.
