Sea-Dog SD-32 20A Resettable Circuit Breaker
Sea-Dog SD-32 20A Resettable Circuit Breaker — Product description
The Sea-Dog SD-32 is a 20 amp resettable circuit breaker built for the wet, vibrating reality of a boat's DC system. Manual reset, an IP66-rated cover, and No. 10-32 stud terminals mean it protects a circuit and stays put. Simple, marine-grade protection you wire in and forget about.
Every DC circuit on your boat needs protection, and the Sea-Dog SD-32 handles that job without any fuss. It's a 20 amp resettable breaker from the Short Stop series, rated for 28 volt DC systems, so it covers the 12V and 24V accessories most of us run. Pop a breaker? Just push the button to reset. No spare fuses to dig for in a hatch at dusk.
The housing is nylon and polycarbonate, and the unit carries an IP66 protection rating with its cover in place. That means it shrugs off spray and washdown, which is exactly what you want on a helm, a console, or back near the batteries. It wires in with No. 10-32 stud terminals, and it meets SAE J553 and J1171 standards for marine and automotive use.
It's sold as a single breaker. Good for bilge pumps, lighting circuits, electronics, and just about any accessory run that pulls up to 20 amps.
