Blue Sea 5052 6-Position CLB Circuit Breaker Block

The Blue Sea Systems 5052 ST CLB Circuit Breaker Block has six quick-connect resettable positions plus an integrated negative bus, rated to 32V DC.

Six positions is the compact block in this family, against the twelve-position 5051 and 5054. For a small DC system or a sub-panel serving one area, six covers the circuits without paying for positions that stay empty.

The common-source design feeds all six circuits from one supply, and the integrated negative bus gives a return point in the same unit. That removes a separate negative bus from the installation, which on a small system is a meaningful saving in space and connections.

Quick-connect clips let compatible CLB breakers snap into place rather than each being mounted and wired separately. Tin-plated copper buses and screw terminals handle the connections, a clear cover with label recesses meets ABYC and USCG requirements, and optional waterproof boots or dress nuts can be fitted over it.
