About this fuse

The Allied Innovations SC-30 is a 30 amp Class G time delay fuse designed for spa electrical systems operating at 480VAC. This OEM replacement fuse provides essential overcurrent protection for high-voltage spa equipment, including pumps, heaters, and control systems. The time delay feature prevents nuisance tripping from normal motor startup surges while maintaining reliable protection against sustained overloads and short circuits.

Built to exact OEM specifications, this Class G fuse ensures perfect compatibility with your spa's electrical panel. Bubbles Supply guarantees an exact fit with same-day shipping and backs every fuse with our comprehensive 1-year warranty. Always verify your spa's voltage requirements and fuse rating before installation, and ensure power is completely disconnected at the main breaker before replacing any electrical components.

Common symptoms this part fixes

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

  • Spa completely dead after power surge
  • Control panel shows no power or error code after overload event
  • Fuse visibly blown, darkened, or element separated on inspection
  • Spa tripped and won't reset after heater or pump fault
  • Repeated GFCI trips traced back to a failed fuse rather than wiring

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

Before you buy — quick checklist

  • Confirm your spa panel calls for a Class G fuse specifically — do not substitute Class H or other fuse classes
  • Verify the blown fuse is rated 30A at 480VAC — check the fuse body or panel diagram
  • Inspect why the original fuse blew before replacing — a fuse blown by an unresolved fault will blow again immediately
  • Confirm this is an Allied Innovations control system or verify your OEM panel accepts this exact fuse type
  • Disconnect power at the main breaker and verify with a multimeter before touching any fuse holder

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