Blue Sea 4321 4 Position Panel with USB and Socket

Description

The Blue Sea Systems 4321 is a 4 position circuit breaker switch panel in gray with a 12V socket and dual USB built in, designed for exposed mounting. Nominal voltage is 12V DC and maximum amperage is 45A.

The 15A circuit breakers are illuminated and do three jobs at once: switching, ON indication and overcurrent protection. That keeps the panel shallow, and the low profile is what makes it fit spaces where a conventional panel with breakers behind switches will not go. Silicone breaker boots and a gasket keep water out.

The face is UV stabilised, flame retardant polycarbonate and ABS that will not corrode. Sizes and mounting follow industry standards, so it retrofits into an existing cutout in most cases. Wiring uses fast-on breaker connectors and a simple two-wire feed with M5 or 10 ring terminals screwed to the bus bars. Stainless 6 by 5/8 inch mounting screws and a set of 15 square format labels are included, with standard and custom labels available separately. Compare with our other marine electrical panels.
