The Blue Sea 2141 Medium Duty Push Button Reset-Only 40A circuit breaker is a purpose-built protection device for marine electrical systems where reliability cannot be compromised. After years on the water, any serious angler or boater knows that electrical failures can strand you miles from the dock—and this weatherproof breaker eliminates that risk by safeguarding critical circuits against dangerous overloads and short circuits. Designed for versatility, the 2141 functions as a main, branch, or 24-hour circuit protector, making it an essential component for sailboats, center consoles, cabin cruisers, and offshore fishing vessels alike.

This 40-amp medium-duty breaker features a trip-free design that ensures the mechanism will open even if the push button is held in the reset position—a critical safety feature when high fault currents are present. The push-to-reset operation is intuitive and requires no tools, allowing crew members to restore power quickly if a breaker trips due to a temporary overload. Its compact footprint (3 x 2 x 7 inches) enables high-density circuit protection configurations, meaning you can protect multiple systems without consuming excessive panel space—a valuable advantage on boats where real estate is always at a premium. Full weatherproofing ensures salt spray, moisture, and marine vibration won't degrade performance over years of service.

Anglers running multi-system vessels—from fish finders and GPS to live wells, trim tabs, and auxiliary pumps—depend on the Blue Sea 2141 to isolate and protect individual loads without killing the entire boat's electrical infrastructure. Installation is straightforward for anyone comfortable with marine wiring; the breaker mounts directly into standard electrical panels and accepts standard marine-grade wire. Whether you're upgrading an aging electrical panel, building out a new console, or adding redundant circuits for critical safety equipment, this 40A breaker delivers the dependable, no-nonsense protection that professional captains and serious recreational boaters have trusted for decades.
