ABB OEM Replacement Contact Kit for Contactors

The ABB OEM Replacement Contact Kit is a contact assembly built to restore reliable switching performance in compatible ABB contactors used throughout commercial and industrial electrical control systems. When contactor contacts become worn, pitted, or damaged from repeated switching cycles, this kit supplies the components needed to bring the contactor back to proper operating condition without replacing the entire assembly. Each kit ships packaged 1 EA, so electrical contractors, maintenance technicians, and facility engineers can stock exactly what is needed for planned maintenance or emergency repairs.

Key Features

Why ABB?

ABB is a recognized manufacturer of industrial electrical control components, and this Contact Kit is built to keep ABB contactors performing reliably across demanding commercial and industrial environments. Choosing a genuine ABB Contact Kit helps ensure a proper fit with compatible ABB contactor assemblies, supporting safe, code-compliant electrical maintenance practices for professional installers and maintenance teams. Stocking OEM contact kits rather than generic substitutes helps preserve the intended operating characteristics of the original contactor assembly, reducing the risk of premature failure after repair. For facilities and contractors standardized on ABB control equipment, this kit offers a straightforward path to restoring contactors to proper working condition using components sourced directly from the original manufacturer.

ABB 546A300G002 – Frequently Asked Questions

1) What is the ABB 546A300G002 contact kit used for?
It is a replacement contact set for compatible ABB contactors. When the main contacts get pitted or worn from repeated switching, the kit restores the contactor instead of forcing a swap of the whole assembly. Typical use is motor control centers and commercial or industrial control panels. It ships 1 EA per package, so one kit is one repair.
2) What part number do I order for this ABB contact kit?
The manufacturer part number is 546A300G002, sold under a single model with no finish, pole, or size options to pick. Quote that number against your contactor's parts list before ordering, since ABB contact kits are matched to specific contactor frames.
3) I have Square D or Eaton contactors, not ABB. What contact kit do I need?
The ABB 546A300G002 kit is for ABB contactors only, so it is the wrong part for another brand's frame. For Square D NEMA contactors there is the 9998SL Series kit, a NEMA Size 2, 3-pole set. On the Eaton side there is the A201 Model J kit for three or four pole Size 1, the 62 Series kit for NACL Size 4 contactors, and the Citation Series C1 kit for 3-pole Size 6-7. Match the brand, NEMA size, and pole count of the contactor you are repairing.
4) Is an auxiliary contact kit the same thing as a replacement contact kit?
No, and this is the most common mix-up when ordering contactor parts. The ABB 546A300G002 is a replacement contact set that restores switching performance in a worn ABB contactor, replacing the power contacts that carry the load. An auxiliary contact kit such as the Eaton C320DPG20, rated 2NO at 10A and 600V, adds signaling or interlock contacts to a contactor for control-circuit duty rather than restoring the main switching contacts. If the contactor is pitted and dropping out, you want the replacement contact kit; if you need an extra normally open contact for a pilot light or seal-in circuit, you want the auxiliary kit.
5) What is the Square D equivalent to an ABB 546A300G002 contact kit?
There is no cross-brand equivalent to the ABB 546A300G002 contact kit, because contact kits are matched to the specific contactor frame they rebuild rather than to a generic rating. The ABB kit is built as a replacement contact set for compatible ABB contactor assemblies and ships 1 EA. On the Square D side, the comparable part is the 9998SL series NEMA contactor replacement contact kit, which is built for NEMA Size 2, 3-pole Square D contactors. Use the 9998SL when the contactor in the panel is a Square D NEMA starter, and the ABB kit when the contactor body is ABB.
6) Should I replace the contacts or just replace the whole contactor?
If the coil, frame, and mechanism are sound and only the contacts are burned or pitted, a contact kit like the ABB 546A300G002 is the standard repair and keeps the existing wiring and mounting untouched. Replace the entire contactor when the coil is failing, the armature or magnet faces are damaged, or the housing is heat-damaged. Contact kits address contact wear from switching cycles, nothing else.
7) Will a generic aftermarket contact kit work in an ABB contactor instead of the ABB part?
The ABB 546A300G002 is produced by ABB for consistent fit and function with compatible ABB contactor product lines, and using OEM contacts preserves the intended operating characteristics of the original contactor assembly rather than altering them after repair. Peer kits in the same repair category are likewise tied to their own platforms, such as the Eaton 6212 for NACL size 4 contactors in the 62 Series. For a facility standardized on ABB control equipment, the ABB kit is the part that matches the contactor it goes into.
8) Should I rebuild the contactor with a contact kit or replace the whole contactor?
A contact kit is the repair path when the contactor body, coil, and enclosure are sound and only the contacts are worn, pitted, or damaged from repeated switching cycles. The ABB 546A300G002 supplies the components to bring an ABB contactor back to proper operating condition without replacing the entire assembly, and it ships 1 EA so maintenance teams can stock it for planned or emergency work. The same logic drives the peer kits for other platforms, such as the Square D 9998SL for NEMA Size 2 3-pole contactors. Replace the whole contactor instead when the coil has failed, the frame is cracked, or the contactor is undersized for the motor load.
9) My contactor is a large frame motor starter. Is the ABB 546A300G002 kit the right size?
Size the kit to the contactor you are rebuilding. The ABB 546A300G002 is the contact set for compatible ABB contactor assemblies used in motor control centers and industrial and commercial electrical panels. Among comparable kits, the frame size is called out in the part identity: the Eaton 6601 covers Citation Series C1 contactors in 3-pole size 6-7, the Eaton 6212 covers NACL size 4, and the Eaton 373B331G09 covers A201 Model J three or four pole size 1. Confirm the nameplate on the contactor first, then order the kit that names that series and size.
10) How many kits should I stock for a panel with several ABB contactors?
Each order of 546A300G002 covers one contactor repair, since the kit is packaged 1 EA. For MRO stocking, count the ABB contactors on your critical motor starters that share this kit and hold one per unit, plus spares for the ones that cycle most often. Contactors switching frequently wear contacts fastest and are the ones that strand a line when they fail.
