Eaton XTMCXFA40 Auxiliary Contact

The Eaton XTMCXFA40 is a front-mounted auxiliary contact block designed for XTRM miniature control relays. It provides four normally open contacts rated at 10 A and 600 V AC. The unit uses screw clamp terminals for secure wiring connections. It suits control panels needing additional switching points for signalling or interlocking.

Capacity and headroom

Four poles give enough contacts for typical auxiliary circuits in motor starters or relay logic. The 10 A AC rating handles standard coil and pilot duty loads without derating. With zero normally closed contacts, it cannot break safety circuits that require positive opening action. The 600 V AC maximum voltage covers most industrial control voltages in use today.

Sequence A mounting format

This block follows the Sequence A configuration for the XT Mini Contactor range. The 2.700 length and transparent housing allow visual confirmation of contact status during commissioning. It installs directly on the front of compatible relays without extra mounting hardware. Buyers needing normally closed contacts or a different sequence must select another variant.

Questions about this item

Will the 600 V AC rating on the Eaton XTMCXFA40 match the control voltage on my existing XTRM miniature control relay?

Yes, the auxiliary contact is rated for up to 600 V AC and is designed to mount on the front of compatible XTRM series miniature control relays.

How can I verify the four normally-open contacts are operating correctly after wiring the screw-clamp terminals?

Apply control power and use a multimeter to check continuity across each of the four poles; all should show a closed circuit when the relay coil is energised.

Does the transparent Eaton XTMCXFA40 come with mounting screws or do I need to order them separately?

The auxiliary contact mounts directly onto the front of the XTRM mini contactor using the contactor's own hardware; no separate screws are included.
