Eaton XTMCXML – Frequently Asked Questions
1) What does the Eaton XTMCXML mechanical interlock actually do in a motor control panel?
It's a mechanical link between two side-by-side contactors that physically stops both from closing at the same time. On a reversing motor starter that means forward and reverse coils can never pull in together, so you don't short two phases if both coils get energized by a wiring fault or a bad control circuit. The XTMCXML works with AC or DC operated magnet systems.
2) Will this interlock fit my Eaton contactors, or is it only for XTRM relays?
The XTMCXML is specified for use with Eaton XTRM miniature control relays. It is not a universal interlock, so if your panel uses a different Eaton contactor family, the interlock for that family is a different part number. Confirm the relays in the panel are XTRM before ordering.
3) Do the two contactors have to be mounted a certain way for the mechanical interlock to work?
Yes. The interlock is built for two contactors mounted horizontally, side by side, with 0 mm distance between them, meaning the two units have to sit directly against each other on the rail. If your layout leaves a gap between the relays or stacks them vertically, the interlock won't span the pair and you'll need to rework the DIN rail spacing.
4) Can I buy just one Eaton XTMCXML interlock?
No. The mechanical interlock ships in packs of 5, and orders have to be placed in multiples of that package quantity. If you only need one reversing starter interlocked, you're still buying five, so the spares go to the shelf.
5) How much room do I need in the enclosure for the Eaton XTMCXML interlock?
It measures 2 in wide, 2 in high and 1.5 in in length/depth. Because it mounts between two abutting relays rather than beside them, it adds no extra rail width, but allow for the depth over the front of the relay bodies when you check door and wireway clearance.
6) Is this interlock rated to any standard for an industrial control panel spec?
The XTMCXML is certified to IEC 60947, the standard family for low-voltage switchgear and controlgear, and it carries CCC marking for China compulsory certification. That covers submittals asking for IEC-rated control accessories and equipment destined for the Chinese market.
7) Does a mechanical interlock replace electrical interlocking in the control circuit?
Think of it as the backstop, not the substitute. The XTMCXML physically blocks both contactors from closing together even if the control wiring or auxiliary contacts fail, which is why reversing starters typically use it alongside electrical interlocking. It is a mechanical accessory only; it carries no contacts of its own.
8) How long will a mechanical interlock last on a relay that cycles constantly?
Eaton rates this interlock for a mechanical life of 2.5 x 10^6 operations, so on a frequently reversing application the interlock is not the limiting part; the contactor's own contact life usually goes first.
