Westinghouse A200 Motor Control to Eaton Cross Reference
The Westinghouse A200 is one of the few industrial products that survived its manufacturer: when Eaton took over the Westinghouse control business, it kept the A200 line — and its catalog numbers — in production. A Westinghouse A200M1CAC on your panel crosses to an Eaton A200M1CAC on ours. The cross-reference work isn’t the starter; it’s everything around it.
That’s what this page covers. Model generations: A-series contactors were built in distinct models, and contact kits and coils are generation-specific — a Model J kit doesn’t universally back-fit earlier models, and for some early generations only contacts and coils remain available at all. Discontinued relatives: the GCA and GPD contactor lines are gone; the A201/A200 series is the designated replacement with shared renewal parts. Heater elements: the FH/H-series heater tables are still the sizing basis for overload replacement — match by element number, not motor amps, when replacing in kind.
MCC buckets: if your A200 lives in a Westinghouse-era MCC (Type W, Series 2100, 5 Star, 11-300), the handle mechanism identifies the MCC type and its replacement-unit path — the identification table is below. The tables map model generations to kit and coil part numbers, GCA/GPD models to A200-series equivalents, and MCC types to renewal-unit guides.
A200-series starters, contact kits, coils, and heaters are core stock for us — Westinghouse-branded originals and current Eaton production both. Send the catalog number and model letter off the nameplate and we’ll match the kit the first time.

1. A200 Model Generations & Renewal Parts
When ordering contact kits or replacement coils, the “Model” letter stamped on the A200 nameplate is critical. Model J and K are the current Eaton generation, while Models A, B, and C are legacy Westinghouse iterations. Kits are often forward/backward compatible only within specific size boundaries.
| Starter / Contactor Size | Model Generation | Contact Kit Note | Coil Replacement Note |
|---|---|---|---|
| Size 00, 0, 1, 2 | Model J / Model K (Current) | Order standard Model J kits (e.g., 672B113G01 for Size 0/1). | Use standard AC coils (e.g., 505C802G01 for 120V). |
| Size 00, 0, 1, 2 | Model A, B, C (Legacy) | Model J kits will not fit Models A, B, or C. Specific legacy kits required. | Legacy coils (e.g., 120V 1A1B) required. |
| Size 3, 4 | Model K / Model J | Size 3 & 4 kits are heavily consolidated. | Verify voltage and frequency; 240V/480V dual-voltage coils common. |
| Size 5, 6 | Model B / Model C | Heavy duty kits (e.g., 185C564G01). Ensure entire stationary/movable assembly is replaced. | Includes coil clearing interlocks. Order as complete assembly. |
2. Legacy GCA/GPD to A200/A201 Cross Reference
The Westinghouse GCA and GPD series were specialized, high-volume iterations of the A-line. Eaton replaced these catalog numbers directly with their A201 (Contactor) and A200 (Starter) equivalents.
| Legacy Device Series | Device Type | Current Eaton Replacement | Cross Reference Note |
|---|---|---|---|
| GCA Series | Non-Reversing Contactor | A201 Series | Matches physical footprint. Order matching NEMA size (00-6). |
| GPD Series | Non-Reversing Starter | A200 Series | Uses same B-type thermal overload relays and FH heaters. |
| GCA…R / GPD…R | Reversing Contactor / Starter | A211 / A210 Series | Reversing units. Confirm horizontal vs vertical mechanical interlock orientation. |
3. FH / H Series Overload Heater Sizing
The A200 series relies on B-type thermal overload relays, which use FH (and legacy H) series heater elements. When replacing a failed heater, always match the FH element number (e.g., FH34) rather than attempting to guess based on motor full-load amps (FLA). Heater charts shift based on enclosure size, starter size, and ambient temperature compensation.
4. Westinghouse MCC Identification & Unit Guides
If your A200 starter is mounted in a vintage Motor Control Center, identifying the bucket and handle type will point you to the correct renewal guide for stabs, doors, and retrofits.
| Visual ID: Handle Mechanism | Legacy MCC Type | Common Starter Installed | Renewal Guide Ref |
|---|---|---|---|
| Heavy Cast Metal (Horizontal/Vertical) | Type W | 11-200, A200 | RP04304008E |
| Vertical Toggle with Lockout | Series 2100 / 5 Star | A200, Advantage | RP04304006E / RP04304007E |
| Slide Operator Mechanism | F2100 | A200, Advantage | RP04304004E |
| Rotary Twist Handle | 9800 Unitrol | A200, Freedom Series | RP04304005E |
