Overview
The Blue Sea Systems 3131 is a surface-mount circuit breaker enclosure for single and double pole breakers. It accepts A-Series toggle breakers plus A-Series and C-Series flat rocker circuit breakers, and the enclosure measures 4.92 in high, 3.95 in wide, and 4.07 in deep.
It gives you a clean way to add a breaker on a flat mounting surface when a flush panel cutout is not practical. Optional LED indicators and square-format labels can be added, which helps keep circuit identification clear at the helm, in a cabin electrical area, or near a dedicated accessory circuit.
This is a sensible fit for refits and small expansion jobs where one breaker needs to stay easy to reach without rebuilding the main distribution panel.
Key features
- Surface-mount enclosure for single and double pole circuit breakers
- Fits A-Series toggle breakers and A-Series or C-Series flat rocker circuit breakers
- Supports optional LED indicators and square-format circuit labels
- Wire glands and fasteners are included for installation
- Compact enclosure size of 4.92 in x 3.95 in with 4.07 in depth
Compatibility and fit
This enclosure is intended for installations built around the breaker styles listed above, so it is worth checking the breaker family before ordering. It is a practical choice when matching an existing Blue Sea Systems setup or when adding a standalone breaker location beside a larger panel.
On board, that usually means a bulkhead, console side, locker wall, or service area where the breaker needs to remain visible and accessible for reset and inspection. Leave enough rear clearance for the enclosure depth and for the wire routing through the glands.
