Blue Sea 9019 AC 240V 63A Rotary Selector Switch

Description

The Blue Sea 9019 AC Rotary Selector Switch provides a compact method of selecting between two 120/240V AC sources when circuit protection is handled elsewhere. Its two-source plus Off configuration is well suited to boats that need to choose between shore power, generator power, or another compatible AC supply feeding one downstream circuit.

The three-pole design switches the appropriate conductors together so the selected source is transferred as one coordinated circuit. Blue Sea uses a heavy-duty industrial-rated rotary mechanism designed for intuitive one-hand operation, and the compact switch body can be mounted in relatively thin electrical panels.

The 9019 is rated for 63A and is UL listed for applications up to 600V AC. Because it is a selector switch rather than a breaker, suitable over-current and leakage protection must still be included elsewhere in the system. For marine electrical panels where space is limited but positive source selection is required, the 9019 provides a robust mechanical solution with a clear Off position between sources.
