It provides two normally-open and two normally-closed instantaneous contacts, rated 10 A at 24 V and derated to 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V.
The 10 A rating at 24 V is the thermal current (Ith) — the continuous current the contacts can carry in free air. For motor control circuits, the switching capacity drops with voltage: at 230 V AC you get 6 A, at 400 V AC it's 3 A, and at 690 V AC it's 1 A. That means this contactor is suited for pilot-duty and control-circuit isolation, not direct motor switching. The 6 kV rated surge voltage resistance (impulse withstand) ensures it holds up against transient spikes on industrial lines without flashover. The shock resistance of 10g / 5 ms and 5g / 10 ms covers most vibration environments on conveyors or machine tools.
The screw and snap-on fastening method lets you clip it onto a DIN rail without tools or bolt it down where vibration is higher.
