Sea-Dog SD-17 80 Amp Circuit Breaker | 830226
Sea-Dog SD-17 80 Amp Circuit Breaker | 830226 — Product description
The Sea-Dog SD-17 is an 80 amp resettable thermal circuit breaker rated to 48 volts DC. It protects a high-current circuit and doubles as a manual switch, so you can kill the load by hand and reset it after a trip without ever touching a fuse.
If you're running a big DC load on your boat, a bow thruster, a windlass, an inverter feed, or a larger trolling and house bank, the Sea-Dog SD-17 gives you the protection that circuit needs in one clean surface-mount package. It's an 80 amp resettable thermal breaker rated to 48 volts DC, which means it covers 12, 24, 36, and 48 volt systems without a second thought.
Here's what we like about it. It's switchable. That means the SD-17 isn't just a breaker sitting quietly in line waiting for a fault. You can flip it by hand to isolate the circuit for service, then flip it back when you're done. And if the circuit ever pulls more than it should, the thermal element trips and cuts the load. You reset it manually once things cool off. No fuses to keep in a drawer, no crimping in a new link at the dock.
The housing is black plastic and it's built to mount on the surface of a panel or bulkhead, so you don't need to cut a big hole to recess it. Power comes and goes through 1/4 inch-28 stud terminals, which give you a solid, high-current connection you can torque down properly. That matters at 80 amps. Loose terminals make heat, and heat is what you're trying to avoid in the first place.
It carries an IP67 protection rating, so it shrugs off dust, spray, and a temporary dunk. That's the rating you want for anything living in a bilge, a console, or an open lazarette where water finds its way in eventually. Sea-Dog builds the SD-17 to SAE J1625, ABYC-E11, UL1077, and SAE J1171 standards, so it lines up with the marine wiring practices a surveyor or an insurer expects to see.
One honest note on sizing. An 80 amp breaker protects the wire and the device on that circuit, so match it to the gauge and the load you're actually running. If you're not sure what amperage your circuit calls for, give us a shout before you order. We'd rather get you the right breaker than send you a return.

Frequently asked questions
Can the SD-17 be used as an on/off switch?
Yes. It's a switchable breaker, so you can flip it by hand to isolate the circuit for service and flip it back when you're done. It's not just a passive breaker waiting for a fault.
What voltage systems does it work on?
It's rated to 48 volts DC, so it covers 12, 24, 36, and 48 volt boat systems. The rating is the maximum, and it works fine on anything below it.
Is it waterproof?
It carries an IP67 rating, which means it's sealed against dust and can handle temporary submersion. That's the protection level you want for a bilge, console, or open lazarette.
How do I reset it after it trips?
It's a manual reset. When the thermal element trips on an overload, you let it cool and then reset it by hand. There's nothing to replace.
What kind of terminals does it use?
Power connects through 1/4 inch-28 stud terminals, so you can torque down a proper ring-terminal cable connection for the full 80 amp load.
How does it mount?
It's a surface-mount unit, so it fastens to the face of a panel or bulkhead. You don't need to cut a recessed opening to install it.
Does it meet marine wiring standards?
Yes. Sea-Dog builds the SD-17 to SAE J1625, ABYC-E11, UL1077, and SAE J1171, so it lines up with the practices surveyors and insurers expect on a boat.
