Blue Sea ST CLB Circuit Breaker Block - 12 Independant Circuits

The Blue Sea Systems ST CLB Circuit Breaker Block (Part Number 5051-BSS) provides a reliable and easy-to-install solution for protecting multiple electrical circuits. Designed to accommodate 12 independent circuits, this surface-mount block features quick connect clips that allow for swift snap-in installation of circuit breakers, streamlining the setup process. The unit utilizes tin-plated copper busbars and screw terminals, ensuring durable and corrosion-resistant connections suitable for marine and other demanding environments. Its clear insulating cover includes square format label recesses, satisfying ABYC and USCG insulation standards, while also offering an easy-to-open clip-on cover for convenient access. Breakouts in the design permit wire access in two directions, facilitating versatile wiring configurations and compatibility with ring terminals for secure connections. Optional waterproof boots or dress nuts can be installed over the cover for enhanced protection against moisture, making this breaker block ideal for wet or splash-prone areas. The design supports square labels, enabling easy circuit identification and maintenance. The Blue Sea ST CLB Circuit Breaker Block is an excellent choice for boat builders and marine electricians seeking a compact, resettable circuit protection system that combines ease of installation with robust performance. It offers a maximum of 32 amps per circuit and supports voltages up to 32V DC, making it suitable for a wide range of marine electrical systems. Its compact size and straightforward design make it an ideal component for integrating into new or existing electrical panels, especially when paired with waterproof switches like the WD Switch Only Panel. This combination helps ensure all circuits are protected from spray and accidental activation, boosting overall safety and reliability in marine applications. The product is expected to be available until February 10, 2026, and carries a Prop 65 warning regarding potential cancer and reproductive harm, a standard consideration for many electrical components used in marine environments.
