About this fuse

The Allied Innovations MDA-10 Slo Blo Fuse is a 10-amp slow-blow electrical protection component designed for spa and hot tub control systems. This OEM-quality fuse provides essential circuit protection for your spa's electrical components, preventing damage from power surges and electrical faults. The slow-blow design allows temporary current spikes during normal operation while still protecting against sustained overloads.

Built to Allied Innovations' exacting standards, this MDA-10 fuse delivers reliable performance you can count on. We guarantee an exact fit for your spa's electrical system, back it with our comprehensive 1-year warranty, and ship same-day to get your spa running quickly. When replacing electrical components, always turn off power at the breaker and consult your spa's wiring diagram to ensure proper fuse rating and placement for safe operation.

Common symptoms this part fixes

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

  • Spa completely dead with no power to board
  • Control panel unresponsive after a surge or fault
  • Spa tripped a fuse rather than a breaker
  • Board powers on but certain components receive no power
  • Repeated nuisance shutdowns traced to a blown low-voltage fuse

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

Before you buy — quick checklist

  • Confirm the blown fuse is rated MDA-10 (10A slow-blow) — do not substitute a fast-blow fuse
  • Inspect the fuse holder and fuse clips for corrosion or heat damage before installing a new fuse
  • Identify why the fuse blew — replacing without diagnosing the root cause will blow the new fuse immediately
  • Check your spa's control board wiring diagram to confirm the correct fuse position and rating
  • Turn off power at the breaker and verify zero voltage with a multimeter before handling any fuses

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