Blue Sea 6337 Switch, AC 120V AC 30A OFF+2 Position

The Blue Sea 6337 Switch, AC 120V AC 30A OFF+2 Position is a compact marine electrical switch designed to manage shore power distribution on vessels equipped with 120-volt AC systems. This selector switch allows boaters to route power from two independent 120V AC shore power sources or a single 240V AC source to two separate load groups, making it an essential component for larger boats and yachts that rely on multiple independent power feeds when docked.

The 6337 switches both the hot and neutral lines for complete circuit isolation, ensuring safe power distribution and eliminating the risk of backfeeding between sources. Rated for 30 amps at 120V AC, this switch handles the typical electrical demands of marine air conditioning units, galley appliances, and cabin systems without requiring an external circuit breaker, provided adequate protection is installed elsewhere in the distribution panel. The compact design makes it an ideal retrofit solution for existing electrical panels where space is limited, and the straightforward OFF+2 position configuration keeps switching logic simple and foolproof during normal operation.

This switch is built for cruising sailors and offshore boaters who split AC loads between different shore power pedestals or need to isolate high-demand circuits when operating in marinas with variable power quality. Weekend fishermen with larger center consoles and overnight cruisers appreciate the reliability that comes from Blue Sea Systems' marine-grade engineering—the company has been the standard for yacht electrical systems for decades. The 6337 is commonly installed in modern cruising sailboats, trawlers, and sport fishing vessels where redundancy and load separation are critical to safe offshore operation.
