About this fuse

The Allied Innovations 25 Amp Fuse SC-25 is a Class G time delay electrical fuse designed for spa and hot tub control systems requiring 25-amp circuit protection. This 480VAC-rated fuse provides reliable overcurrent protection for spa equipment including pumps, heaters, and control boards in commercial and residential installations.

Engineered to exact OEM specifications, this time delay fuse prevents nuisance tripping while protecting your spa's electrical components from damage. At Bubbles Supply, we guarantee an exact fit with same-day shipping and back every fuse with our comprehensive 1-year warranty. Proper electrical safety is critical—always turn off power at the breaker and consult your spa's wiring diagram before replacing any fuse to ensure correct amperage rating and compatibility.

Before you buy — quick checklist

Confirm the blown fuse in your spa is rated 25A — check the fuse holder label or wiring diagram, never assume
Verify your system calls for a Class G time delay fuse specifically, not a fast-blow type
Check that your fuse block or holder accepts the SC (ferrule/cylindrical) form factor
Inspect the fuse holder and surrounding wiring for burn marks or melted insulation before replacing — a fuse that keeps blowing indicates an underlying fault
Always turn off power at the breaker and verify with a multimeter before handling any fuse or electrical component

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