It carries three normally open instantaneous contacts and no delayed or make-before-break switching, so it's a straightforward signal repeater: when the coil pulls in, all three NO contacts close at the same instant. Rated 10 A at 24 V, 6 A at 230 V, and 1 A at 690 V, it covers the typical control-voltage spread you'd find in a panel — 24 VDC for PLC outputs, 230 VAC for motor control centers, and 690 V for high-voltage switching gear. The 6 kV surge voltage resistance means it holds up against the transients that come with inductive loads in the same cabinet.
That matters when the auxiliary contactor is feeding a PLC input that sees milliamps; a lesser contactor might oxidize and miss the signal. Shock resistance of 10g / 5 ms and 5g / 10 ms means it survives the vibration of a closing breaker or a nearby motor start without chattering the contacts. The RoHS compliance date of 07/01/2006 confirms it meets the EU directive.
