About this product

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.
