Restoring the Switching Contact Assembly
The Allen-Bradley 100-DCE-140 is a renewal-parts kit for the main contacts of a Bulletin 100-D140 IEC contactor fitted with an electronic coil. It is intended for contact replacement during maintenance rather than as a complete contactor assembly.
The main contacts carry the electrical load switched by the contactor. With repeated operation, contact surfaces can deteriorate through electrical wear and switching activity. Replacing the contact components can help restore the contactor's switching assembly without requiring replacement of the entire device, provided the contactor remains suitable for continued service.
Rockwell Automation identifies 100-DCE-140 specifically for the electronic-coil 100-D140 contactor. The catalog distinguishes it from the conventional-coil renewal part, 100-DC-140.
Compatibility Is Determined by the Contactor Version
The 100-DCE-140 designation contains an important distinction: the DCE renewal parts are intended for electronic-coil versions of the 100-D contactor range.
For the 140 A frame, the relevant comparison is:
| Renewal part | Intended contactor |
|---|---|
| 100-DCE-140 | 100-D140, electronic-coil version |
| 100-DC-140 | 100-D140, conventional-coil version |
Although both kits serve the same contactor frame size, they should not be treated as interchangeable without checking the installed contactor and its parts documentation.

What the Kit Provides
Rockwell's Bulletin 100-D renewal-parts documentation describes the main-contact renewal parts as three complete sets for three-pole contactors.
This makes the 100-DCE-140 a component-level maintenance purchase. It is not a complete 100-D140 contactor, and it should not be confused with an arc-chamber replacement or terminal-hardware kit.
When preparing a maintenance order, confirm that the requirement is for the main contacts rather than another renewal component in the same contactor family.
When to Consider Main Contact Renewal
This part is relevant when servicing a compatible 100-D140 contactor and the maintenance inspection identifies wear or deterioration in its main-contact assembly.
Typical maintenance considerations include:
- Contact surfaces showing electrical wear or damage
- Contact replacement specified during a scheduled overhaul
- Restoration of a compatible 100-D140 contactor without replacing the complete device
- Spare-parts planning for equipment using electronic-coil 100-D140 contactors
The condition of the contactor's remaining components should also be assessed. Replacing the main contacts alone does not resolve problems caused by damaged arc chambers, coil faults, mechanical wear or other contactor defects.
Before Ordering: Three Details to Confirm
Contactor frame: Verify that the installed contactor is a 100-D140.
Coil version: Confirm the electronic-coil configuration. The conventional-coil renewal part carries the different catalog number 100-DC-140.
Replacement scope: Check that the maintenance requirement is for the three-pole main-contact renewal set, not a complete contactor or another renewal-parts kit.
Frequently Asked Questions
What is Allen-Bradley 100-DCE-140?
It is a main-contact renewal kit for the electronic-coil version of the Allen-Bradley 100-D140 IEC contactor.
How many contact sets are included?
Rockwell's renewal-parts documentation specifies three complete sets for the three-pole contactor application.
Can 100-DCE-140 be used with 100-D140 conventional-coil contactors?
The conventional-coil version uses the separate 100-DC-140 renewal-parts number. Confirm the installed contactor version before ordering.
Is this a complete contactor?
No. It is a replacement main-contact set, not a complete contactor assembly.
What is the UPC for this item?
The supplied UPC is 781180164880. The catalog number 100-DCE-140 should also be used when matching the part against Rockwell documentation.
