Blue Sea 3121 SMS Panel Enclosure with ELCI and Blanks

Description

The Blue Sea Systems 3121 pairs a 16A ELCI main with three blank positions on 230V AC. Not every European-standard installation is pulling heavy current, and on a smaller boat or a berth with modest shore service a 16A main is the honest size. Fit it within 10 feet of the AC inlet and it satisfies ABYC E-11.

The blanks take Carling Technologies A and C Series flat rocker breakers, so branch circuits can go in as loads get added instead of committing to the full layout on day one. One red reverse polarity LED and three green ON LEDs are installed for 230V AC, and the label positions come backlit from the factory.

Build is the same as the rest of the SMS line. Glass filled polycarbonate base, clear cover so you can check breaker status without breaking the seal, overlapping cover profile, and an oversized polyurethane gasket formed in place for a continuous seal rather than a joined one. The stainless hinge pin comes out for easier fitting and the stainless latch secures the cover without penetrating the enclosure. It measures 6 by 6 by 4 inches, 7.6 by 7.4 by 4.7 overall, and ships with five waterproof glands, labels, mounting hardware and an instruction manual. Compare the rest of our marine electrical panels.
