Eaton XTCEXFAC11 Auxiliary Contact

The Eaton XTCEXFAC11 is a front-mounted auxiliary contact block designed for XT Frame B-C control relays. It provides one normally open and one normally closed contact rated at 16 A AC with a maximum voltage of 500V AC. Screw clamp terminals allow secure wiring in industrial control panels. This accessory expands the switching capability of compatible Eaton XTRE series relays.

For Panel Builders Using XT Frame B-C Relays

This block suits engineers adding auxiliary signalling or interlocking to existing XTRE control relays in Frame B or C sizes. The front-mount design simplifies installation without removing the base relay. Buyers needing DIN-rail mount contacts, higher pole counts, or contacts for different relay series should look at alternative accessory lines.

Sustained Load Behaviour

Under continuous 16 A AC operation the contacts maintain reliable switching within the 500V AC rating. Screw clamp terminals resist loosening from vibration during extended duty cycles. The transparent housing permits visual inspection of contact status without panel removal. Performance remains consistent across the rated electrical life of the device.

Questions about this item

What control relay series must I already own for this front-mount auxiliary contact to fit?

It is compatible with Series XTRE control relays, so one of those must be installed.

Will the 500 V AC rating and 16 A capacity work with the older contactors I am keeping in the panel?

Yes, the contact handles up to 500 V AC at 16 A, matching many legacy Eaton contactors of the same frame size.

How can I verify the 1NO/1NC contacts change state correctly after wiring the screw clamp terminals?

Operate the associated relay and measure continuity across each contact pair — one should close, the other open.
