About this relay/contactor

The Allied Innovations 50 Amp 240V Contactor 3PC-240 is a heavy-duty electrical switching component designed for spa and hot tub control systems. This 3-pole, single-throw (3PST) contactor operates on a 240VAC coil and handles up to 50 amps, making it suitable for controlling high-power spa equipment like pumps, heaters, and blowers in residential and commercial spa applications.

Built to Allied Innovations' exacting OEM standards, this contactor delivers reliable switching performance for years of trouble-free operation. At Bubbles Supply, we guarantee this is the exact replacement part your spa needs, backed by our comprehensive 1-year warranty and same-day shipping on in-stock items. The 240V coil voltage and 50-amp capacity make this contactor ideal for larger spa systems requiring robust electrical control. Always verify your existing contactor's specifications and ensure power is disconnected before installation.

Common symptoms this part fixes

Before you buy — quick checklist

Confirm your existing contactor is 3-pole (3PST) — not 2-pole or 4-pole
Verify coil voltage is 240VAC, not 24VAC or 120VAC — check the label on the old contactor body
Confirm load amperage rating matches 50A — do not substitute a lower-rated contactor
Check terminal layout and overall footprint against your control box mounting position
Disconnect all power at the breaker and verify with a multimeter before handling the contactor
Identify whether the contactor failed electrically (coil) or mechanically (welded/pitted contacts) before ordering

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