Sea-Dog SD-17 60A 48V DC Circuit Breaker | IP67
Sea-Dog SD-17 60A 48V DC Circuit Breaker | IP67 — Product description
The Sea-Dog SD-17 is a 60-amp resettable thermal circuit breaker for marine DC circuits. Rated up to 48 volts, sealed to IP67, and built to ABYC and UL1077 standards, it protects high-draw gear and resets by hand in seconds.
The Sea-Dog SD-17 is a resettable thermal circuit breaker built to protect a single high-current circuit on your boat. It's rated for 60 amps at up to 48 volts DC, which means it drops right into 12V, 24V, 36V, or 48V systems without a second thought. If you've got a windlass, a bow thruster, an inverter feed, or a heavy trolling motor lead that needs its own protection, this is the kind of breaker you reach for.
Here's how it works. When the current climbs past 60 amps for too long, the thermal element heats up and trips the breaker, cutting power before your wiring cooks. Instead of hunting for a blown fuse, you just reset it by hand once the fault's cleared. The switchable design also lets you use it as a manual on/off switch, so you can kill a circuit at the panel when you're servicing gear or leaving the boat for the season.
It's sealed to IP67, so it shrugs off spray, rain, and washdown. That matters when you're mounting near the helm, in a console, or anywhere the weather finds its way in. The black plastic body is made for surface mounting, and the 1/4 inch-28 stud terminals take standard ring terminals for a clean, high-current connection that won't back off with engine vibration.
Sea-Dog built this one to the specs that matter for marine electrical work. It meets ABYC E-11, UL1077, and SAE J1625 and J1171, so it satisfies the standards your surveyor and your insurance company care about. Whether you're rigging a new panel or replacing a tired breaker that keeps nuisance-tripping, the SD-17 gives you dependable overcurrent protection you can reset in seconds.
One quick note. This is sold as a single breaker, so if you're protecting several circuits, order one per circuit. Match the amp rating to the load and the wire gauge, and you're set.

Frequently asked questions
What amp rating is the Sea-Dog SD-17?
It's a 60-amp breaker. Match it to a circuit whose wiring is sized for 60 amps or more so the breaker trips before the wire overheats.
What voltage systems does it work with?
It's rated up to 48 volts DC, so it works on 12V, 24V, 36V, and 48V DC systems.
Is the SD-17 waterproof?
It carries an IP67 protection rating, so it stands up to spray, rain, and washdown when mounted in an exposed spot.
How do I reset it after it trips?
It's a manual reset. Once the overload or fault clears, press the reset to restore power. The switchable design also lets you use it as an on/off switch for the circuit.
How does it mount and wire up?
It's a surface-mount breaker with 1/4 inch-28 stud terminals that accept standard ring terminals. Bolt it to a flat surface and land your ring terminals on the studs.
Does it meet marine electrical standards?
Yes. It's built to ABYC E-11, UL1077, SAE J1625, and SAE J1171, the standards that apply to marine branch-circuit protection.
