Sea-Dog 40A Inline Resettable Circuit Breaker 420844-1
Sea-Dog 40A Inline Resettable Circuit Breaker 420844-1 — Product description
This Sea-Dog inline resettable circuit breaker guards a 40-amp circuit on your boat and resets with the push of a button. Rated for 12-volt AC and 24-volt DC systems, it's a compact way to protect a pump, windlass, or accessory run without ever hunting for a spare fuse.
Fuses do the job, but they're a pain when one lets go in a chop and you're digging through a bin for a spare. This Sea-Dog inline circuit breaker skips all that. When it trips, you press the manual reset button and you're back in business.
It's rated for 40 amps and works on 12-volt AC or 24-volt DC systems, so it covers most of the accessory and pump circuits you'd wire on a small or mid-size boat. The housing is nylon and polycarbonate, so it shrugs off the damp and salt air down in a bilge or behind a console. Connections are brass #10-32 studs with nuts, which give you a solid, corrosion-resistant landing for ring lugs.
At 1-5/16 inches wide and 1-7/16 inches tall, it tucks into tight spots behind the dash. Wire it inline on the positive lead, close to the battery or the load you're protecting. Sold as a single breaker.
