Eaton XTCEXFAC40 Auxiliary Contact
The Eaton XTCEXFAC40 is a front-mount auxiliary contact block designed for Series XTRE control relays. It provides four normally open contacts rated at 16 A and 500 V AC. Screw clamp terminals ensure secure wiring for industrial control circuits. The transparent housing allows visual inspection of contact status.
Suited for expanding control relay functions
This accessory suits panel builders adding auxiliary signalling or interlocking to compatible XTRE relays. It is not intended for applications requiring normally closed contacts or configurations with fewer than four poles. Installers needing different contact arrangements or rear-mount options should select an alternative accessory.
Four normally open contacts at 16 A
The defining specification is the provision of four normally open poles, each rated 16 A at 500 V AC. This contact count and current rating determine whether the block meets the control circuit design requirements. Verify the relay series compatibility before installation.

Questions about this item
Should I choose the 4 normally-open version or a different contact mix?
This block provides four normally-open contacts with no normally-closed circuits, giving you four independent make-paths in a single front-mount unit.
What does the 16 A rating mean when the contact is installed in a control panel?
The contacts are rated for 16 A AC continuous current, so each pole can carry that load in a 500 V AC control circuit without derating.
How does the screw-clamp terminal interface limit wire size and torque?
Screw-clamp terminals accept solid or stranded conductors and are tightened to the manufacturer’s specified torque, securing the wire without a separate ferrule.
