Sea-Dog SD-13 5 Amp Thermal Circuit Breaker
Sea-Dog SD-13 5 Amp Thermal Circuit Breaker — Product description
The Sea-Dog SD-13 is a 5 amp push-to-reset thermal circuit breaker for marine DC panels. It protects a single branch circuit, resets with a button push, and carries ignition-protected UL1500 certification for safe install near fuel vapors.
The Sea-Dog SD-13 is a 5-amp push-to-reset thermal circuit breaker built for marine panels and low-voltage DC circuits on the boat. It protects a single branch, think a bilge pump, a nav light run, or an electronics feed, and when it trips you just push the button to reset. No fuses to carry, no spares to lose in the bottom of a drawer.
The body is Bakelite with screw terminals, so wiring it in is straightforward. It mounts through a panel with only 3/16 inch of depth behind the face, which makes it easy to fit on a tight dash or a small switch panel where you don't have much room to work. Rated 250 volts AC and 50 volts DC, it covers the common low-voltage circuits you'll run on most boats.
What really matters out on the water is the listing. It's UL 1077 listed and carries UL/cUL ignition-protected UL1500, so it's safe to install in spaces where gas or fuel vapors could be present, like near the engine or in a fuel-tank compartment. That's the part you don't want to skip.

Frequently asked questions
What does the 5 amp rating protect?
It protects a single branch circuit drawing up to 5 amps, which covers smaller loads like a bilge pump, a nav light run, or an electronics feed. Match the breaker to the wire gauge and the load on that circuit.
How do I reset it after it trips?
Just push the white button in. The SD-13 is a push-to-reset breaker, so there are no fuses to replace. If it trips again right away, check the circuit for a short or an overload before resetting.
Is it safe to install near the engine or fuel tank?
Yes. The SD-13 is ignition protected to UL1500, so it's rated for installation in spaces where gasoline or fuel vapors could be present, such as the engine compartment or near the fuel tank.
What voltage can it handle?
It's rated for 250 volts AC and 50 volts DC, which covers the standard 12-volt and 24-volt DC circuits you'll find on most boats.
