Blue Sea 5052 6-Position CLB Circuit Breaker Block

Description

The Blue Sea 5052 ST CLB Circuit Breaker Block provides six compact resettable breaker positions plus an integrated negative bus for marine DC distribution. Quick-connect clips allow compatible CLB breakers to snap into place, simplifying assembly compared with individually mounting and wiring six separate breakers.

Tin-plated copper buses and screw terminals provide conductive, corrosion-resistant connections. The common-source design distributes power across all six circuits, while the negative bus provides a convenient return point for connected loads. The block supports substantial total current and individual circuit loads when correctly sized breakers and conductors are used.

A clear insulating cover satisfies applicable ABYC and USCG insulation requirements and includes square-format label recesses for circuit identification. Wire-entry breakouts allow routing from two directions, and optional waterproof push-button boots or dress nuts can be fitted over the cover. For compact DC systems needing six resettable circuits and an integrated negative return bus, the 5052 provides a clean modular distribution solution.
