Overview
The Blue Sea Systems 1210 is a 120V AC 4-position panel for managing branch circuits on board. It is rated for 120V AC service, supports up to 100A at the panel, and fits into a compact footprint with a height of 4.75 in, width of 4.88 in, and depth of 3.00 in.
This panel gives you four breaker positions in a format that works well where space is limited but clean AC distribution still matters. All circuit label positions are backlit, and each circuit position has an ON indicator LED, which makes it easier to check circuit status from the helm, inside the cabin, or in other lower-light areas on board.
It is supplied with four single-pole 15A A-Series flat rocker circuit breakers and a basic AC label kit, so the panel arrives ready for a straightforward branch-circuit layout. This is part of the 360 Panel System, which uses an open-frame approach that can make panel planning easier when you are building out or updating an AC section.
Key features
- Four 120V AC branch positions for a compact onboard distribution setup
- 100A maximum panel amperage when the installation uses correctly sized wire and overcurrent protection
- Backlit circuit label positions for easier identification at night or in enclosed spaces
- ON indicator LEDs in every circuit position for quick visual status checks
- Includes four 15A single-pole A-Series flat rocker circuit breakers
- Includes 4206 basic AC label kit with 30 black square labels
- Compact 4.75 in x 4.88 in face size with 3.00 in depth for tighter mounting areas
- Compatible with the 360 Panel System layout
Compatibility and fit
This panel is intended for 120V AC marine electrical systems. It is a practical choice when you need a small branch panel for a few dedicated AC loads or when you are adding an extra AC distribution point in a boat that already has a main shore power or generator feed handled elsewhere.
Before ordering, confirm that your system is 120V AC, not 12V or 24V DC, and check that your mounting location has enough clearance for the 3.00 in depth behind the panel. The panel amperage rating also needs to be matched with the wire size and overcurrent protection used in the installation.
Installation and setup
The included breakers and label kit help keep the layout clean from the start, which is useful when you want circuits identified clearly for troubleshooting and routine checks. A panel like this suits owners, yards, and refit projects that want a compact AC branch panel with labeled circuits and visible status indication rather than a blank panel that still needs to be built out.
