Front Auxiliary Contact for XT Mini Relays

The Eaton XTMCXFA11 is a front-mount auxiliary contact block designed for XTRM miniature control relays. It adds one normally open and one normally closed contact to the base relay, expanding switching capability for control circuits in industrial panels.

Sequence A replacement for standard auxiliary blocks

This Sequence A block replaces a basic auxiliary contact when a specific contact arrangement or mounting position is required. The upgrade is worth it when the control scheme demands a dedicated 1NO/1NC pair at the front of the relay for accessibility or wiring layout reasons.

Handles 10 A AC at 600 V with screw terminals

The two-pole block carries up to 10 A AC at a maximum of 600 V AC, suitable for standard pilot duty and interlocking tasks. It runs out of headroom for loads exceeding the 10 A rating or voltages above 600 V AC, and it is not intended for direct high-power switching applications.

Questions about this item

Will the 4.000 Sequence A front auxiliary contact fit the XTRM miniature control relay mounting pattern?

Yes, it is compatible with Series XTRM Miniature Control Relays and mounts on the front with screw terminals.

How do I install the front auxiliary contact, and what step do installers often miss?

Mount it on the front of the XTRM relay and secure the screw terminals; the step often missed is verifying the Sequence A orientation before tightening.

When will the 10 A rated contacts need replacement?

The 1NO/1NC contacts are rated for 10 A AC at 600V; replace them when switching performance degrades or after reaching their rated electrical endurance.
