Sea-Dog 420810-1 Thermal AC/DC Circuit Breaker, 10 Amp, Stamped Brass/Molded Bakelite

The Sea-Dog 420810-1 is a 10 amp thermal AC/DC circuit breaker built for reliable overcurrent protection on boat electrical panels. Constructed of stamped brass with a molded bakelite housing, it provides a durable, corrosion-resistant switching element suited to the marine environment. The breaker is UL Listed (A-0701), giving buyers a recognized safety certification for AC and DC circuit protection. Its compact footprint makes it a straightforward drop-in for panels and electrical enclosures where space is limited, and its low weight keeps it easy to handle and install. As a single-pole breaker rated at 10 amps, it is intended for use in circuits sized to that load, protecting wiring and connected equipment from overcurrent conditions by interrupting the circuit when the rated amperage is exceeded. Sea-Dog Line has manufactured marine hardware and electrical components since 1933, and the 420810-1 reflects that long-running focus on boat-specific parts.
