The Blue Sea 187-Series 80 Amp Circuit Breaker Surface Mount is the marine electrical workhorse every serious boater needs in their power distribution system. After years on the water, you know that reliable circuit protection isn't optional—it's essential to keeping your vessel safe and operational. This single-device unit combines both switching and circuit protection functions, eliminating the need for separate components and simplifying your electrical panel layout.

Built with Blue Sea's proven "Trip Free" design, this 80-amp breaker cannot be held in the ON position during a fault condition—a critical safety feature that prevents you from overriding protection when an electrical problem occurs.

The 0.58 lb weight makes it easy to integrate into tight electrical compartments, and its compact footprint doesn't consume excessive panel real estate.
