Blue Sea 5054 12-Position CLB Circuit Breaker Block

Description

The Blue Sea 5054 ST CLB Circuit Breaker Block provides twelve compact resettable circuit positions plus an integrated negative bus for marine DC distribution systems. It is designed around quick-connect CLB breakers, allowing compatible breakers to snap into place without the wiring complexity of mounting each breaker separately.

Tin-plated copper buses and screw terminals provide conductive, corrosion-resistant connections, while the common-source design simplifies power distribution across the twelve circuits. The block supports up to 100A total and up to 32A per individual circuit when installed with appropriate wiring and protection.

A clear insulating cover satisfies applicable ABYC and USCG insulation requirements and includes square-format label recesses for circuit identification. Breakouts allow wire entry from two directions, and optional waterproof boots or dress nuts can be installed over the cover. For compact DC systems that need many resettable circuits and a built-in negative return point, the 5054 provides a clean distribution platform. Compare with our other bus bars & power distribution.
