Sea-Dog 20A Inline Resettable Circuit Breaker | 420842-1 — Product description

The Sea-Dog inline resettable circuit breaker is the simple way to protect a 20 amp DC circuit. It trips on a short or overload, then resets with a push of the button. No spare fuses to carry.

Every DC circuit on your boat needs protection, and the Sea-Dog inline resettable circuit breaker is a simple way to give it. Rated at 20 amps, it trips when a wire shorts or a pump stalls, then resets with a push of the button instead of sending you digging for a spare fuse.

It's built to live out there. The nylon and polycarbonate housing shrugs off spray and damp bilge air, and the brass #10-32 studs and nuts give you a solid, corrosion-resistant connection. Wire it inline on accessory runs like bilge pumps, livewell pumps, lights, or electronics. It's rated for 12 volt AC and 24 volt DC circuits.

It's compact, roughly 1-5/16 by 1-3/8 by 1-7/16 inches, so it tucks in behind a panel or under the console without eating up space. And the manual reset button keeps you in control. Push it back in and you're running again.

Just push the manual reset button back in. Once the fault that tripped it is cleared, power flows again. No tools, no spare fuses.

How does it wire in?

It goes inline using the brass #10-32 studs and nuts on each end. It's compact enough to sit behind a panel or under the console.

Is this a single breaker?

Yes, this is sold as a single breaker.
