Overview
The Blue Sea Systems 1408 is a 12V DC battery management and circuit breaker panel that combines an M-Series Dual Circuit Plus battery switch, a 100A main breaker, and three branch circuit positions in one vertical layout. It separates the engine circuit from the house circuit, allows emergency cross-connect between isolated battery banks, and helps reduce voltage sag to electronics during engine cranking.
The panel face measures 7.75 x 4.88 inches with an installed depth of 3.50 inches, so it works where space is limited but you still want the switch and circuit protection gathered in one spot. Backlit label windows and ON indicator LEDs make the panel easier to read at the helm, inside a cabin, or in a dim electrical space.
Key features
- 12V DC battery management panel with one 100A main breaker and three branch circuit positions
- Built-in M-Series Dual Circuit Plus battery switch isolates engine and house banks and allows emergency cross-connect
- Three push-button reset-only 15A branch breakers are included for protected circuits where switching is handled elsewhere
- Backlit label positions and ON indicator LEDs at each circuit help with low-light checks and troubleshooting
- Vertical panel footprint measures 7.75 x 4.88 inches with 3.50 inches of depth behind the mounting surface
- Front-access labels and snap-on end plates make service work simpler and keep the finished panel looking tidy
Compatibility and fit
This panel is for 12V DC systems and suits boats that keep start and house batteries separate. The branch positions use reset-only breakers, so they fit installations where the load is switched somewhere else or where the circuit stays available as a 24-hour feed.
It is a good match for owners who want the battery switching point and main DC protection in one panel instead of spreading those parts across different locations. Before ordering, confirm the mounting cutout, the 3.50 inch behind-panel depth, and the current needs of the branch circuits you plan to protect.
Installation and setup
Labels can be removed and replaced from the front, which makes future circuit changes easier after the panel is mounted. Snap-on end plates cover the mounting screws, so the finished installation looks cleaner on a visible bulkhead or helm panel.
