Blue Sea 9077 AC 240V 65A Rotary Selector Switch

Description

The Blue Sea 9077 AC Rotary Selector Switch is a heavy-duty source-selection switch for marine AC systems that need to choose between two incoming 120/240V power sources. It allows one AC circuit to be connected to either source while providing a positive Off position between selections.

The three-pole design switches both current-carrying lines and the neutral conductor, making it suitable for 120/240V systems where full source isolation is required. Blue Sea uses an industrial-rated rotary mechanism designed for intuitive one-hand operation, and the compact body can be installed in relatively thin electrical panels when circuit protection is provided elsewhere.

The switch is rated for 65A operation and is UL listed for applications up to 600V AC. Because it is a selector rather than a circuit breaker, appropriate upstream or downstream over-current protection must still be included in the electrical design. For boats that need a straightforward method to choose between shore power, generator power, or another compatible AC source, the 9077 provides a compact and mechanically clear switching solution.
