Motor Control · Product Selection Guide

A model-level checklist for selecting Eaton contactors correctly—especially coil voltage, auxiliary contact configuration and motor-duty ratings.

For contactors, the complete catalogue number matters. Two models with the same current rating can differ in coil voltage, auxiliary contacts, mounting details and motor-duty ratings, which can make them unsuitable as direct substitutes.

Quick answer: The table below contains XTCE model examples; it is not a DILM part-number table.

At a glance

• The table below contains XTCE model examples; it is not a DILM part-number table.
• Verify coil voltage and frequency from the full suffix and current datasheet.
• In the supplied XTCE examples, 10 indicates one NO auxiliary contact and 01 indicates one NC contact.
• Check AC-3 motor duty, overload relay compatibility, mounting and accessories before replacement.

1. Compare the exact family and model code

DILM and XT are Eaton low-voltage contactor product designations that appear in motor-control documentation. The important distinction for ordering is not simply “old versus new”: the exact model code identifies current rating, pole count, coil, auxiliary contacts and compatible accessories. Some XTCE catalogue codes are cross-referenced to DILM model descriptions in Eaton documentation, so check the manufacturer’s current cross-reference rather than assuming the names are interchangeable across every configuration.

A mismatch in the supplied draft has been corrected

The model table contains XTCE part numbers, not DILM part numbers. The revised table therefore labels them as XTCE examples. The XTCE032C10G code is shown with one normally-open auxiliary contact (1 NO), while XTCE032C01G is shown with one normally-closed auxiliary contact (1 NC); the source draft had the 10G configuration described incorrectly.

2. XTCE model examples

The 040D00G coil specification is listed by Eaton as 190 Vac at 50 Hz / 220 Vac at 60 Hz. For other listed suffixes, verify the complete manufacturer data sheet rather than inferring coil voltage from the family alone.

3. Coil voltage and frequency are order-critical

A contactor can have the correct operational current and still be unusable if the coil voltage or frequency is wrong. Compare the actual control supply with the exact coil code on the part number, including 50 Hz / 60 Hz differences and whether the coil is AC or DC. Do not reduce a model number to its base family when requesting a quote or preparing a replacement order.

• Read the coil code from the full catalogue number and verify it against the product data sheet.
• Check the control transformer or PLC output supply and its tolerance.
• For a replacement, record the installed coil marking; do not rely only on the cabinet drawing.

4. Auxiliary contacts: 01 and 10 are not the same

In the supplied XTCE examples, the 10 variant corresponds to one normally-open auxiliary contact and the 01 variant to one normally-closed auxiliary contact. The 00 variant in the XTCE040D00G example has no built-in auxiliary contact. This matters when the contactor state is used for PLC feedback, electrical interlocking or status indication. Confirm whether the application requires NO, NC or a separate auxiliary block.

5. Size for motor duty, not just headline amps

For motor applications, compare rated operational current at the actual operating voltage and utilization category (commonly AC-3 for normal squirrel-cage motor starting and switching). Also check motor power, starting frequency, ambient temperature, enclosure conditions, overload relay compatibility and the required short-circuit coordination. A headline ampere figure without its rating conditions is not a complete selection basis.

6. Contactor selection checklist

1. Confirm the load type and utilization category.
2. Match rated operational current and motor power at the installation voltage.
3. Match coil voltage, frequency and AC/DC type.
4. Choose the required main poles and auxiliary contact configuration.
5. Confirm mounting, terminals, overload relay and other accessories.
6. Verify the full catalogue number and replacement cross-reference with Eaton documentation.

Frequently asked questions

No. Current alone does not establish interchangeability. Check coil voltage, auxiliary contacts, dimensions, terminals, accessories and motor-duty ratings.

For the supplied XTCE examples, 01 indicates one normally-closed auxiliary contact and 10 indicates one normally-open auxiliary contact. Confirm the exact model datasheet.

Do not generalize a suffix across all families or markets. Use the complete part number and the corresponding manufacturer datasheet.

Need help matching a part number?

Provide the complete DILM/XTCE code, motor voltage and power, coil supply, auxiliary-contact requirement and installed dimensions. That is the minimum useful information for a reliable cross-reference.

Before ordering: confirm the complete catalogue number, regional approvals, electrical ratings and compatible accessories in the latest manufacturer documentation.
