Square D 31063409 Type S Replacement Contactor Coil, 310 Series

The Square D Type S Replacement Contactor Coil, 310 Series, lets electricians and panel builders quickly swap the coil in a Type S contactor or starter to convert it to a different control circuit voltage or NEMA size application. This coil family is available in two configurations: 208VAC 60Hz for NEMA Size 3 starters, and 440/480VAC 50/60Hz for NEMA Size 2 starters, covering a broad range of Type S contactor and starter rebuild needs. Depending on the option selected, the coil is compatible with class 8903 type SQ lighting contactors, class 8502 type SE contactors, and class 8910 type DPA12/SYD138 contactors. Replacing the coil restores or reconfigures the unit for its intended control voltage without the added cost of sourcing a whole new contactor or starter.

Key Features

  • Coil Voltage / NEMA Size Range: Available in 208VAC 60Hz - NEMA Size 3 or 440/480VAC 50/60Hz - NEMA Size 2 configurations to match the starter being serviced.
  • NEMA Size Compatibility: Designed for 2 or 3 pole NEMA Size 2 or Size 3 starter and contactor configurations, depending on the option selected.
  • Type S Replacement Coil: Purpose-built replacement coil for Type S contactors and starters, part of the 310 Series.
  • Broad Compatibility: Fits class 8903 type SQ lighting contactor, class 8502 type SE contactor, and class 8910 type DPA12/SYD138 contactor assemblies.
  • Cost-Effective Upgrade: Converts an existing contactor or starter to a different control circuit voltage without replacing the entire unit.
  • Manufactured by Schneider Electric: Produced under the Square D brand by Schneider Electric to consistent quality standards.

Square D 3106340957 – Frequently Asked Questions

1) Can I use a Square D Type S coil to change my contactor's control voltage instead of buying a new contactor?
That is exactly what this coil is for. Swapping the coil in a Type S contactor or starter reconfigures it to a different control circuit voltage without sourcing a whole new unit, which is the usual repair path for electricians and panel builders servicing NEMA Size 2 and Size 3 equipment. The coil itself is the voltage-defining part, so pick 208VAC 60Hz or 440/480VAC 50/60Hz depending on the control circuit you are landing on it.
2) Will this Square D coil fit a class 8903 type SQ lighting contactor?
Yes, depending on the option selected. The Type S 310 Series coil family is stated as compatible with class 8903 type SQ lighting contactors, class 8502 type SE contactors, and class 8910 type DPA12/SYD138 contactors. Confirm the coil voltage marked on the coil you are pulling out of the lighting contactor and order the matching configuration.
3) My coil is burned out on a 480V control circuit. Is the 440/480V version the right replacement?
For a 440/480VAC control circuit on a Type S NEMA Size 2 unit, the 440/480VAC 50/60Hz coil, MPN 3106340957, is the one to pull. It is rated for both 50Hz and 60Hz, so it suits export panels and domestic installations alike. If the unit is a Size 3 frame instead, the available option in this family is the 208VAC 60Hz coil.
4) Can an ABB CR460XC replacement coil be used in place of a Square D 31063409 Type S coil?
No. The Square D 31063409 is a Type S replacement coil in the 310 Series, built to drop into Square D Type S contactors and starters and into class 8903 type SQ lighting contactor, class 8502 type SE contactor, and class 8910 type DPA12/SYD138 assemblies. The ABB CR460XC is a replacement coil for ABB CR460XC series lighting contactors. Coils are matched to the magnet and frame of their own contactor line, so each one goes back into the brand and series it was built for rather than crossing between them.
5) Does this coil work on 2 pole and 3 pole contactors?
It covers 2 or 3 pole NEMA Size 2 or Size 3 starter and contactor configurations, depending on which option you select. Pole count does not change the coil; the coil voltage and the frame size do, so verify the Size 2 or Size 3 frame and the control voltage stamped on the old coil.
6) Is there a replacement lighting contactor coil option from another brand if I am not running Square D gear?
If your lighting contactor is ABB rather than Square D, the ABB CR460XC Series lighting contactor replacement coil is the equivalent repair part for that line. Coils are not cross-brand interchangeable, so match the coil to the contactor manufacturer and series, then to the control voltage.
7) I am rebuilding a lighting contactor. Which replacement coil matches which contactor line?
Match the coil to the contactor brand and series on the can. For a Square D lighting contactor, the Square D 31063409 Type S coil covers class 8903 type SQ lighting contactors along with Type S contactors and starters, in 208VAC 60Hz for NEMA Size 3 or 440/480VAC 50/60Hz for NEMA Size 2. For an ABB lighting contactor in the CR460XC series, the coil is the ABB CR460XC series replacement coil. Confirm the control circuit voltage of the existing coil before ordering so the new coil matches the control wiring.
8) Who makes Square D Type S coils and where are they built?
Square D is a Schneider Electric brand, and these 310 Series Type S coils are produced under it. Country of origin is Mexico. For an MRO buyer standardizing spare coils across a facility, that matters for documentation and for keeping genuine OEM parts in the crib rather than aftermarket substitutes.
