Blue Sea 4374 WeatherDeck 4 Position Breaker Panel

The Blue Sea Systems 4374 is a WeatherDeck 4-position circuit breaker panel in gray, rated IP67, with 15A per circuit at 12V and a 45A cumulative rating.

Breaker and switch are separate here, using four 7056 push button reset-only breakers alongside four 4150 SPST toggle switches. So switching a circuit off does not involve resetting anything, and a breaker that has tripped stays visibly tripped rather than being confused with a switch left off.

The green label backlighting behaves differently from an ON indicator and this is worth knowing before fitting. The labels light whenever the panel is powered regardless of switch positions, so backlighting says the panel is live rather than which circuits are running.

The backlight has its own circuit, works with Blue Sea digital dimmers and draws 10mA per illuminated circuit. IP67 covers temporary immersion up to 30 minutes, the panel mounts in four orientations at 4.3 by 4.25 by 3.5 inches, and the 4215 waterproof DC label kit with 30 labels is included.
