Blue Sea 5054 12-Position CLB Circuit Breaker Block

The Blue Sea Systems 5054 ST CLB Circuit Breaker Block has twelve resettable positions and an integrated negative bus, rated 100A total and 32A per circuit.

Quick-connect CLB breakers snap into place rather than each being wired and mounted separately, which is the labor saving here. Twelve individually mounted breakers means twelve sets of connections and twelve chances to get one loose. One block replaces all of that with a common source.

The integrated negative bus gives a return point in the same unit, removing another separate component from the installation. Tin-plated copper buses and screw terminals handle the connections, with breakouts allowing wire entry from two directions.

Resettable breakers rather than fuses means no spares to carry and no fuse to find in the dark. A clear insulating cover satisfies applicable ABYC and USCG insulation requirements with square-format label recesses, and optional waterproof boots or dress nuts can be fitted over it. Maximum 32V DC. Explore more bus bars and power distribution.
