Blue Sea 5050 ST CLB Circuit Breaker Block - 6 Position

The Blue Sea 5050 ST CLB Circuit Breaker Block – 6 Position is a marine-grade electrical distribution component designed for demanding offshore and vessel applications where reliable power management is mission-critical. This six-position circuit breaker block integrates rapid-deployment quick-connect clips that allow individual breakers to snap securely into place without tools, reducing installation time and eliminating the fumbling associated with manual fastening under field conditions.

Construction centers on tin-plated copper bus bars and heavy-duty screw terminals, both critical specifications in salt-air and corrosive environments where standard brass or unplated copper would deteriorate rapidly. The unit features a clear insulating cover with square-format label recesses, satisfying ABYC and USCG insulation requirements—essential compliance standards for marine electrical systems. The easy-open clip-on cover design permits quick access for maintenance or circuit modifications without partial system disassembly. Breakouts allow wire routing in two directions, accommodating varied panel layouts, and the block accepts ring terminals for secure, low-resistance connections.

This breaker block serves vessel operators, marine technicians, offshore support crews, and recreational boaters managing multi-circuit power distribution systems. It's the standard choice for retrofit electrical upgrades, emergency power reconfiguration, and installations where compact footprint and modular expandability matter. Optional push-button waterproof boots or dress nuts are available for additional environmental protection, making this unit adaptable to exposed weather or splash-prone mounting locations.

Blue Sea Systems is the recognized authority in marine electrical distribution, and the 5050 block is part of their core lineup for professional-grade vessel power management. Whether upgrading a working fishing boat or managing complex electrical routing on a tactical support vessel, this six-position block delivers the durability and standardized integration marine operators expect.
