Sea-Dog SD-13 7A Thermal Circuit Breaker
Sea-Dog SD-13 7A Thermal Circuit Breaker — Product description
The Sea-Dog SD-13 is a 7 amp thermal circuit breaker with a simple push-to-reset button. It's ignition protected to UL1500, so you can mount it safely on a boat's DC panel or in an engine compartment.
The Sea-Dog SD-13 is a thermal circuit breaker built to protect a single low-amp branch on your boat's DC panel. It trips on overload, then you push the white button to reset. No fuse to dig for, no spare to carry. At 7 amps it's sized for accessory runs like nav lights, a bilge pump, or a small electronics circuit that draws steady but modest current.
What makes it worth having on the water is the certification. It's ignition protected to UL1500, so it's safe to mount in an engine compartment or anywhere fuel vapors could collect. The Bakelite housing handles heat and won't flinch at vibration. Terminals are 1/4 inch quick connect, so you can wire it in with standard spade connectors and skip the soldering iron.
It's a panel-mount unit with a shallow 3/16 inch panel depth, so it fits tight dash spaces behind a console. Rated for 250 volt AC and 50 volt DC. If you're rigging a new switch panel or replacing a tired breaker, this is a clean, honest part that does one job well.

Frequently asked questions
What does the 7 amp rating mean for wiring?
It means the breaker trips when the circuit pulls more than 7 amps. Match it to a low-draw load like nav lights, a small pump, or an electronics circuit. Don't put it on a high-current run it can't handle.
Is this breaker safe to mount near the engine?
Yes. It's ignition protected to UL1500, which means it won't ignite fuel vapors. That makes it safe for engine compartments and other spaces where fumes can collect.
How does it reset after it trips?
You just push the white button back in. It's a push-to-reset design, so there's no fuse to replace and nothing to carry as a spare.
Will it fit behind a tight dash panel?
It should. The panel depth is only 3/16 inch, so it mounts in shallow spaces behind a console or switch panel. It uses 1/4 inch quick connect spade terminals.
