The Blue Sea Systems 3131 Surface-Mount Circuit Breaker Enclosure is a compact, durable housing designed to organize and protect single- and double-pole circuit breakers in marine, RV, and industrial electrical systems. Built for easy surface installation, the 3131 simplifies panel layout while supporting optional indicators and clear circuit identification.
Ideal for marine electrical panels and other compact installations, this Blue Sea Systems enclosure helps reduce panel clutter while providing secure mounting for breakers. The enclosure is well-suited for saltwater and mobile environments when used as part of a proper marine electrical system, and its accessory accommodation makes it easy to add status LEDs and labeled circuit IDs for safer, faster troubleshooting.
Specifications and compatibility are important when planning a panel. Packaged dimensions are approximately 9" L x 6" W x 4" H with a packaged weight of about 0.85 lb. The 3131 is compatible with standard A-Series toggle and A/C-Series flat rocker breakers and works with common marine electrical accessories. For wiring and mounting details, consult Blue Sea Systems documentation and the owner's manual (UPC 632085031312).
