Eaton XTRE10B40A – Frequently Asked Questions

1) What contact arrangements does the Eaton XTRE10B control relay come in?

Two arrangements across the XTRE10B range: a 4NO-0NC / 2NO-2NC type (models XTRE10B22A, XTRE10B22C and XTRE10B40A) and a straight 2NO-2NC type (XTRE10B22E). If your circuit needs two break contacts for interlocking or fault logic, take a 2NO-2NC version; if you only need make contacts for seal-in and multiplying a signal, the 4NO build gives you four normally open poles.

2) Which coil voltages are offered on the Eaton XT 45 mm control relay?

Coil options run 110/120 volts (XTRE10B22A), 120 volts (XTRE10B40A) and 415-480 volts (XTRE10B22C). Match the coil to your control transformer secondary, not to the line voltage feeding the panel. Ordering a 415-480 V coil for a 120 V control circuit leaves the relay unable to pull in.

3) How much current can the Eaton XTRE10B relay contacts carry?

Conventional thermal current is 10 A per contact. That covers typical control-circuit duty, pilot lights, solenoid valves, PLC input multiplication and coil circuits for downstream contactors. It is not a motor switching device; for motor loads use a contactor with an overload, and let the relay drive that contactor's coil.

4) What is the closest alternative to the Eaton XTRE10B control relay if I need a 120 VAC coil with a 3 NO + 2 NC contact arrangement?

The Eaton XT IEC control relay is offered with 4NO-0NC / 2NO-2NC contact arrangements, including a 110/120 volt coil version (XTRE10B22A) and a 120 volt coil version (XTRE10B40A), so a five-pole 3 NO + 2 NC arrangement is not part of the XT range. For that arrangement, the Square D TeSys Deca control relay CAD32G7 is built as a 3 NO + 2 NC device with a 120 VAC coil. Choose based on the contact count your control circuit logic needs: two normally closed contacts with the Eaton 2NO-2NC, or three normally open plus two normally closed with the TeSys Deca.

5) Will the Eaton XT control relay fit my existing panel layout and DIN rail spacing?

The relay uses the 45 mm standard frame, so it lines up with the rest of the Eaton XT control relay line for consistent panel layout. Overall body is 3 in wide by 3 in deep by 2 in high, which is the space to allow in the wireway layout.

6) Does the Eaton XTRE10B use screw terminals or spring cage connections?

Screw terminals. For machinery and MCC work that is usually what the spec calls for, since a torqued screw connection holds up under vibration and can be re-torqued during PM. If your panel standard calls for push-in or spring clamp terminations, this is not the right build.

7) What is the difference between the Eaton XTRE10B and a Square D TeSys Deca control relay?

Both are IEC-style control relays for panel and machine control circuits. The Square D unit we carry, the TeSys Deca CAD32G7, is a 3 NO + 2 NC relay with a 120 VAC coil, so it gives you a five-pole mix. The Eaton XTRE10B comes as either four-pole 2NO-2NC or 4NO. Pick by the pole count and mix your schematic actually needs, and keep the brand consistent with whatever else is already in the enclosure so spares stay simple.

8) Can I use a control relay instead of a contactor for my machine circuit?

Use the relay for logic, the contactor for load. The XTRE10B is rated at 10 A conventional thermal current and is built for control circuit switching, interlocks, and multiplying contacts in industrial machinery, motor control centers and automation systems. Anything drawing real motor current belongs on a contactor sized to the load, with the relay driving its coil.

9) Can a Square D TeSys Deca relay be swapped directly into a panel wired for an Eaton XT control relay?

Not as a bolt-in swap. The Eaton XT control relay uses a 45 mm standard frame with screw terminals and a 10A conventional thermal current rating, and its terminal layout follows the XT series so it lines up with other XT components in the same panel. The Square D CAD32G7 belongs to the TeSys Deca series, a different manufacturer platform with its own mounting and terminal marking. Replacing one with the other means re-landing the control wiring and confirming the new device fits the DIN rail space and panel layout you already have.

10) We standardize our motor control centers on one control relay platform. What favors the Eaton XT over the Square D TeSys Deca?

The Eaton XT control relay is UL Listed and uses a 45 mm standard frame size, which keeps mounting and panel layout consistent across the XT line, so contactors and relays in the same series share a footprint in a motor control center. It is stocked in several coil voltages, including 110/120 volts, 120 volts, and 415-480 volts, which lets a facility cover both low-voltage and higher control-power circuits from one series. The Square D CAD32G7 is part of the TeSys Deca series and would standardize a facility around that platform instead. The practical decision is which series the rest of your contactors and starters already come from.

11) Where can I get the full Eaton XTRE10B specifications for my submittal package?

Eaton publishes a spec sheet for the XT control relay, hosted at https://zensupply.com/content/pdf/eaton/spec-sheet-d4caeb.pdf. That is the document to attach when a submittal or an engineer's review needs the manufacturer data behind the 45 mm frame size and contact ratings.
