About this fuse

The Allied Innovations SC-20 is a 20-amp Class G time delay fuse designed for spa electrical systems operating at 600VAC. This OEM replacement fuse provides essential overcurrent protection for spa control systems, pumps, and other electrical components. The time delay feature prevents nuisance tripping from normal motor startup surges while still protecting against sustained overcurrent conditions.

When your spa's electrical protection fails, this exact OEM replacement ensures reliable operation and safety. We guarantee an exact fit for your Allied Innovations electrical system, with same-day shipping on in-stock orders and a full 1-year warranty for complete confidence. As Canada's spa parts authority, we stock only genuine OEM components that meet original equipment specifications. Always verify amperage requirements match your spa's electrical specifications before installation, and consult a qualified electrician for proper fuse replacement procedures.

Before you buy — quick checklist

Confirm the blown fuse is rated SC-20 — check the fuse body or your control board documentation before ordering
Verify the fuse holder in your control box accepts a Class G fuse form factor
Do not upsize the amperage — always replace with the same 20A rating as specified by the OEM
Investigate why the fuse blew before replacing — a fuse that fails repeatedly indicates an underlying fault (shorted pump, wiring issue, bad capacitor)
Disconnect all power to the spa at the breaker before handling any fuse components

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