About this relay/contactor

The Allied Innovations SPC-120 is a 115V contactor designed for spa electrical systems requiring reliable SPST (Single Pole, Single Throw) switching control. This 25-amp rated contactor features a 115VAC coil and handles the electrical demands of spa pumps, heaters, and other high-current components in residential and commercial hot tub applications.

Built to OEM specifications, this contactor delivers the exact fit and performance your spa system needs. At Bubbles Supply, we guarantee precise fitment and back every SPC-120 with our comprehensive 1-year warranty. Most orders ship the same day, getting your spa back up and running quickly. When installing any electrical component, always turn off power at the breaker and verify wiring connections match your spa's electrical schematic before energizing the system.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

Spa component fails to energize despite control signal being sent
Heater or pump cycles off unexpectedly under load
Audible click from contactor but component does not power on
Contactor coil energizes but contacts fail to close
Burned or welded contacts causing component to stay on continuously
Spa control board sends call but load circuit stays dead

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

Confirm your spa's control circuit is 115VAC — this coil is not compatible with 240V control voltage
Verify your existing contactor is SPST configuration, not DPST or DPDT
Check the amp rating of the load being switched does not exceed 25A
Inspect terminal style and spacing on your existing contactor to confirm wiring connections are compatible
Document or photograph your current wiring before removal — terminal labeling varies by spa brand
Confirm this is a contactor failure and not a control board output issue before ordering

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
