Blue Sea Systems e-Series Dual Circuit Plus Battery Switch 5511E, 350A, 32V DC, Dual Battery Bank

The Blue Sea Systems e-Series Dual Circuit Plus Battery Switch, part number 5511E, is a dual battery bank switch built for inboard and outboard powered boats running alternators up to 120A. It switches two battery banks simultaneously while maintaining battery bank isolation, and lets the operator combine the two banks together in the event of a low start battery. The switch's compact design makes it practical to install in tight spaces, and it offers multiple mounting options, including surface mount or mounting to the rear of a panel. It is ignition protected, so it can be installed in the engine room of a gasoline powered boat.

Electrical connections are made through one piece copper studs measuring 7/8 inch long, which accept multiple cable connections and hold up to the tinned copper contacts inside the switch for a secure electrical path. The switch operates in ON-OFF-COMBINE mode through a rotary actuator with a normally closed contact type, and the face has tactile textures so the operator can identify the switch position by feel in low light or no light conditions. The housing carries an IP66 rating, protecting the switch against powerful water jets. This model does not include an alternator field disconnect.
