Sea-Dog SD-17 60A 48V DC Circuit Breaker | Panel Mount
Sea-Dog SD-17 60A 48V DC Circuit Breaker | Panel Mount — Product description
The Sea-Dog SD-17 is a 60-amp resettable thermal circuit breaker built for 48-volt DC marine circuits. It panel-mounts clean into a helm or electrical panel, and the switchable reset lever lets it double as a manual on/off switch. Sealed to IP67, it shrugs off spray and washdowns where a lesser breaker would corrode.
The Sea-Dog SD-17 is a 60-amp resettable thermal circuit breaker sized for 48-volt DC systems. It's the part that sits between your battery bank and a high-draw circuit, tripping before a fault turns into melted insulation or worse. When it trips, you reset it by hand and you're back in business. No fuses to hunt for, no spares to keep in a baggie under the console.
What makes the SD-17 handy is the switchable reset. The lever doesn't just reset after a trip, it works as a manual on/off switch too. So you can kill power to a circuit for service, or isolate a load over the winter, without pulling a terminal. Flip it off and the circuit's dead. Flip it on and you're powered up. That's one less switch to wire into the panel.
At 60 amps and 48 volts DC, this one's built for the bigger loads. Think electric drive circuits, high-output accessory banks, and 48-volt house systems on larger boats. It panel-mounts through a single hole and lands power on a 1/4 inch-28 stud terminal, so you're torquing down a proper ring terminal instead of trusting a push-on spade. The black plastic housing keeps it low-profile on the dash or inside an electrical panel.
Sea-Dog sealed this breaker to IP67, which means it handles dust and temporary immersion. Out on the water that translates to spray, rain, and washdowns without the contacts corroding out from under you. It's certified to SAE J1625, ABYC-E11, UL1077, and SAE J1171, so it meets the marine standards a surveyor or insurer looks for. If you're wiring to ABYC, this checks the box.
Buy the one breaker you need and wire it in. It's a single unit, not a multi-pack, so order the count that matches your circuits. And if you're not sure whether 60 amps is right for your load, size it to the wire gauge and the manufacturer's draw rating before you commit.

Frequently asked questions
Can the SD-17 be used as an on/off switch?
Yes. The switchable reset lever works as a manual on/off switch as well as resetting after a trip. Flip it off to kill power to the circuit for service or storage, then flip it back on when you need it.
What voltage and amperage is this breaker rated for?
It's rated for 60 amps at 48 volts DC. That makes it a fit for higher-voltage systems and high-draw circuits rather than a small 12-volt accessory.
Is the SD-17 waterproof?
It carries an IP67 protection rating, so it handles dust and temporary immersion. In practice that means spray, rain, and washdowns won't corrode the contacts, but it isn't meant to sit submerged permanently.
How does the SD-17 mount?
It's a panel-mount breaker. It drops through a single hole in a helm, dash, or electrical panel, and power lands on a 1/4 inch-28 stud terminal that takes a ring terminal.
What marine standards does it meet?
It's certified to SAE J1625, ABYC-E11, UL1077, and SAE J1171. If you're wiring to ABYC or need documentation for an insurer or surveyor, it meets those standards.
Does this come as a single breaker or a multi-pack?
It ships as a single breaker, not a multi-pack. Order one per circuit you're protecting.
