Blue Sea Systems 4320 Contura Water-Resistant Circuit Breaker Switch Panel, 4 Position, Gray

The Blue Sea Systems 4320 is a 4-position Contura water-resistant circuit breaker switch panel built to give consolidated control and circuit protection for up to four DC-powered accessories, including bilge pumps, on 12V or 24V DC systems. Each position uses an illuminated 15A circuit breaker that combines switching, ON indication, and overcurrent protection in a single rocker, so the operator can see at a glance which circuits are live and reset a tripped breaker without tools. The panel is rated for a maximum operating amperage of 45A and terminates with 1/4 inch male quick connect terminals plus an M5 (#10) ring terminal size for the supply connection.

The panel surface is molded from polycarbonate/ABS that is UV-stabilized and flame retardant, and it will not corrode in a marine environment. Silicone breaker boots and a watertight mounting gasket seal each switch against water ingress; with the gasket installed, the panel front carries an IP66 rating, protecting against powerful water jets. The panel ships in a gray finish sized to industry-standard dimensions and mounting centers, so it drops into an existing panel cutout without modification. Installation hardware -- stainless steel #6 x 5/8 inch mounting screws -- and 15 common square circuit labels are included along with instructions, so the panel is ready to label and wire for its intended circuits out of the box.
