Blue Sea 8361 AC Rotary Switch Panel 65 Ampere 3 Positions + OFF, 3 Pole

The Blue Sea Systems 8361 AC Rotary Switch Panel is a heavy-duty marine electrical distribution component designed for vessels requiring reliable multi-source AC power switching. This 65-ampere, 3-pole rotary switch with OFF position manages up to three separate 230-volt AC sources, making it an essential control hub for boats with generator, shore power, and inverter systems that must operate independently or in controlled sequence.

Built from heavy 1/8-inch aluminum 5052 alloy with a two-part polyurethane slate gray finish, this panel withstands salt air corrosion and UV degradation common to marine environments. The unit incorporates a 9011-series heavy-duty industrial-rated rotary switch mechanism, red reverse-polarity LED indicators to warn of wiring errors, and green power-available LEDs that confirm voltage presence on each connected source. The 3-position-plus-OFF configuration allows operators to select among three AC sources or isolate the system entirely, preventing backfeeding between incompatible power sources—a critical safety feature when switching between generator and shore power without a transfer switch lockout.

This panel suits larger cruising sailboats, trawlers, and motor yachts where multiple AC power sources demand manual or operator-controlled selection. Serious liveaboards and offshore cruisers who manage generator run time, rely on shore power at marinas, and operate inverters for anchorage use benefit from the visibility and positive control this rotary switch provides. The compact footprint addresses space constraints typical of marine electrical installations while maintaining the amperage capacity and contact reliability required for continuous duty.
