Eaton Auxiliary Contact, 4 Contact, 3 NO/1 NC, DILM, Front, 16 A, 220 V dc, 500V ac, 277949 DILM150-XHI31

This auxiliary contact from Eaton sends a signal to your controller to let it know when a contactor switches, giving you convenient circuit monitoring. As the device works with Eaton's DILM contactors (such as 631-9899), it's widely compatible with standard switching equipment. The unit's 4 poles monitor 4 circuits at once, so you can be sure of efficient system coverage. As it mounts directly onto your contactor's front plate, the block is quick and easy to install. You can use auxiliary contacts like this one with electric motor starters and commercial lighting systems.

• Screw terminals achieve secure electrical connections that protect against jostling

This block has a service life of around 1.3 million operations, so you can be sure of long-lasting performance.

You can use this unit with both AC and DC inputs, for versatility.
