Blue Sea 8690 e-Series Dual Circuit Plus Panel

Description

The Blue Sea Systems 8690 e-Series Dual Circuit Plus, part number 5511e, is the two circuit version of Blue Sea’s twin engine battery management panel. It carries one 100A C-Series flat rocker breaker for main DC protection and two 15A push button thermal breakers for 24 hour circuits.

Two protected always-on circuits is the entry point in this family, and for a lot of twin engine boats it is the honest number: bilge pump and bilge alarm, with everything else switched. If the list is longer than that, the Plus 2 versions add a third and fourth.

The panel isolates the engine circuit from the house circuit so each bank discharges on its own and a drained house bank still leaves you able to start. An emergency cross connect is there when that goes wrong anyway. Keeping the two sides separate also shields electronics from the sags and spikes that cranking pushes through the system. Battery switch operation is simpler than a conventional arrangement, and adding an Automatic Charging Relay makes charging across both banks automatic. The 4218 square format labels and 4140 24 hour round labels are included. See more marine electrical panels.
