Product details

It carries 2 normally-open instantaneous contacts and 2 normally-closed instantaneous contacts, rated for a mechanical life of 30 million operations typical. The contactor is rated 10 A at 24 V and derates across higher voltages: 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — so the voltage class of your control circuit directly governs the continuous current it can handle.

The screw and snap-on mounting allows quick DIN-rail installation or direct panel screwing. Shock resistance is 10 g for 5 ms and 5 g for 10 ms.

The auxiliary switch block is field-extendable, so additional contact blocks can be added to the side of the base unit. The part is RoHS compliant per the 2006/07/01 substance prohibition date. No UL or CSA listing is recorded; verify site-specific approval requirements with your electrical inspector.
