Square D Type S Replacement Coil, 31041400 Series, NEMA Size 00/0/1

The Square D Type S replacement coil (31041400 Series) lets you convert or restore the control circuit voltage of an existing Type S contactor or starter without replacing the entire unit. This coil is available in control circuit voltages ranging from 24VAC 60Hz to 208VAC 60Hz, letting you select the exact coil voltage your application requires, while the host contactor/starter carries a Ue Rated Operational Voltage of 208V AC 60Hz and is sized for NEMA Size 00, 0, and 1 applications. It is compatible with Class 8502 Type SA (Series A)/SB/SC contactors, Class 8903 Type SM lighting contactors, and Class 8536 Type SA (Series A)/SB/SC starters, making it a cost-effective option for industrial and commercial control panel maintenance.

Square D 3104140020 – Frequently Asked Questions

1) Can I change the control circuit voltage on an existing Type S contactor by swapping just the coil?
That is exactly what the 31041400 coil is for. Swapping the coil converts or restores the control circuit voltage of an existing Type S contactor or starter without replacing the whole unit. Coil voltage choices run from 24VAC 60Hz to 208VAC 60Hz, so you can match the control transformer or control source you already have in the panel.
2) Which coil voltages can I actually order for the Square D 31041400?
Two coil voltages are offered: 24VAC 60Hz, ordered as part number 3104140020, and 208VAC 60Hz, part number 3104140048. Pick by the voltage of your control circuit, not the motor line voltage. Both are 60Hz only, so a 50Hz control source is not a match.
3) I have a NEMA Size 00/0/1 starter but it is not a Square D. What replacement coil do I use?
The 31041400 only fits Square D Type S units in Classes 8502, 8903 SM, and 8536. For an ABB magnet coil in the same NEMA Size 00/0/1 range, the ABB 15D2 Series replacement magnet coil is the equivalent. On Eaton gear, the coil follows the starter line: the Freedom Series replacement coil for Freedom starters, the A200/A201 AC renewal coil for A200/A201, and the GCA 530 coil for Size 5 Type GCA. Match the brand and series stamped on the contactor.
4) I need a replacement coil for a lighting contactor, not a motor starter. Which one should I order?
The Square D 31041400 Type S coil does cover lighting contactors on the Square D side, since it is listed as compatible with Class 8903 Type SM lighting contactors in addition to 8502 contactors and 8536 starters. If the lighting contactor is an ABB unit instead, the peer built for that duty is the ABB CR460XC series lighting contactor replacement coil. Choose by the nameplate of the contactor you are servicing.
5) Is there an equivalent replacement coil for NEMA Size 00, 0, and 1 contactors from another manufacturer?
The Square D 31041400 Type S coil is configured for NEMA Size 00/0/1 contactors and starters. The closest peer by application is the ABB 15D2 series replacement magnet coil, which is also described for NEMA Size 00/0/1. Coils are not interchangeable between manufacturers' magnet assemblies, so the ABB 15D2 belongs in ABB contactors and the 31041400 belongs in Square D Class 8502 Type SA (Series A)/SB/SC contactors, Class 8536 Type SA/SB/SC starters, and Class 8903 Type SM lighting contactors. Match the coil to the host line, then match the control circuit voltage.
6) Will a Square D 31041400 coil work in an Eaton Freedom series starter?
No. The Square D 31041400 Type S coil is intended for Square D Class 8502 Type SA (Series A)/SB/SC contactors, Class 8536 Type SA/SB/SC starters, and Class 8903 Type SM lighting contactors. For an Eaton Freedom series starter, the corresponding part is the Eaton Freedom series replacement coil rated 120/110V at 60/50 Hz. Coil bobbin dimensions, terminal arrangement, and magnet gap differ between the two lines, so they are not cross-fit parts.
7) My contactor is a NEMA Size 5 — can I use the 31041400 coil?
No. The Square D 31041400 coil is sized for NEMA Size 00, 0, and 1 frames. For a Size 5 frame, the peer in the set is the Eaton Type GCA 530 Size 5 replacement coil rated 200V/208V 60Hz, which suits an Eaton GCA 530 host. Coils are frame-size specific because the magnet and bobbin must match the armature they pull.
8) Does the 208VAC coil option mean the contactor itself is limited to 208V?
The host Type S contactor or starter carries a Ue rated operational voltage of 208V AC 60Hz regardless of which coil voltage you select. So the 24VAC coil does not change the power-side rating, and the 208VAC coil is not what sets it either. Coil voltage is purely the control circuit choice.
9) How much control transformer capacity do I need to pull in this Square D Type S coil?
Size the control transformer for the inrush, not the holding load. The coil draws 245 VA inrush and settles to 27 VA average sealed consumption. On a 24VAC circuit that inrush is what trips an undersized transformer or a marginal PLC output relay, so account for it along with any other coils energizing on the same circuit.
10) Can I use this coil on a lighting contactor, or do I need a lighting-specific coil?
For Square D Class 8903 Type SM lighting contactors, the 31041400 coil is the listed replacement, and voltage conversion on those lighting contactors is one of its stated applications. If you are working on an ABB lighting contactor instead, the coil to look at is the ABB CR460XC Series lighting contactor replacement coil, not this one. Coils are not interchangeable across brands.
11) Is replacing the coil worth it, or should I just replace the whole starter?
If the contacts and the enclosure are sound and only the coil is burned out, or the control voltage needs to change, the coil is a field-replaceable part that drops into the existing Type S unit and saves buying a complete contactor or starter. Common uses are motor control panel retrofits and repairs, OEM panel building, and general industrial and commercial starter maintenance. If the power contacts are pitted or welded, the coil alone will not fix it.
12) I need a 240V coil — does the 31041400 cover that?
No. The Square D 31041400 Type S coil is offered across a 24VAC to 208VAC 60Hz range, with 24VAC 60Hz and 208VAC 60Hz coils available. If the control circuit is 240V 60Hz and the device is an Eaton D26 relay, the matching peer is the Eaton D26 relay replacement coil rated 240V 60Hz. For a Square D Type S host on a higher control voltage, stay within the Type S coil family rather than cross-fitting a relay coil.
13) Can I replace a bad coil instead of the whole starter, and what are the alternatives?
Yes — a coil swap is the usual repair. The Square D 31041400 is a field-replaceable contactor coil for Size 00/0/1 Type S units, measuring 3.21 in wide, 2.15 in high, and 1.9 in deep, and it also lets you change the control circuit voltage of an existing unit without replacing it. The same approach applies on other lines: ABB offers the 15D2 magnet coil for Size 00/0/1 and the CR460XC coil for lighting contactors, and Eaton offers the A200/A201 renewal coil and the Freedom series coil. The deciding factor is the brand and frame of the device already in the panel.
14) What are the dimensions of the Square D 31041400 replacement coil?
The coil measures 3.21 in width, 2.15 in height, and 1.9 in depth. Useful if you are checking clearance in a crowded enclosure or confirming the part you pulled out is the same physical size before you order.
15) Where is the Square D 31041400 coil made?
Country of origin is Mexico. It is a Square D product manufactured by Schneider Electric, which matters for buyers with domestic-content or origin documentation requirements on a bid.
