Sea-Dog SD-32 30A Resettable Circuit Breaker | Short Stop
Sea-Dog SD-32 30A Resettable Circuit Breaker | Short Stop — Product description
The Sea-Dog SD-32 is a 30 amp resettable circuit breaker built for the wet, vibrating world of a boat's DC system. It protects a single circuit up to 28 volts, resets by hand, and ships with a cover for an IP66 seal.
Every DC circuit on your boat needs protection, and the Sea-Dog SD-32 handles that job for loads up to 30 amps at 28 volts. It's a Short Stop style resettable breaker, so when it trips you don't go hunting for a spare fuse. You just push the reset button and you're back in business.
The housing is nylon and polycarbonate, which shrugs off the salt, spray, and UV that eat cheaper hardware alive. Wiring is straightforward with a No. 10-32 stud terminal, and the included cover brings it up to an IP66 rating so splash and washdown don't get inside. It carries SAE J553 and J1171 ratings, the marine ignition-protection standard, so it's safe to run near gas engine spaces.
Use it on bilge pumps, livewells, accessory panels, or any single circuit where you'd rather reset a breaker than replace a blown fuse. It's a small part that saves you real headaches down the line.

Frequently asked questions
What does the SD-32 protect?
It guards a single DC circuit rated up to 30 amps at 28 volts. Wire it inline on things like bilge pumps, livewells, or an accessory panel to stop overloads and shorts before they cause damage.
How do I reset it after it trips?
It's a manual reset breaker. When it trips, you just press the reset button by hand to restore the circuit. There's no fuse to replace.
Is it safe to mount near a gas engine?
Yes. It carries SAE J553 and J1171 ratings, and J1171 is the marine ignition-protection standard, so it's built not to spark in a way that's a hazard in engine spaces.
Is it waterproof?
With the included cover it reaches an IP66 protection rating, so it stands up to spray and washdown. The nylon and polycarbonate housing handles the marine environment well.
