Blue Sea Systems 7183 285-Series 50A Surface Mount Breaker

Blue Sea Systems 285-Series Surface-Mount 50A Circuit Breaker (7183-BSS / 7183)

The Blue Sea Systems 7183-BSS (Catalog SKU: 7183) is a compact, medium-duty 285-Series Surface-Mount 50A Thermal DC Circuit Breaker designed to provide overcurrent protection and manual load switching for auxiliary circuits, windlasses, trolling motors, and sub-panel feeds. Operating on DC networks up to 48 V DC, it acts as a direct drop-in replacement for legacy 185-Series circuit breakers.

Housed in a weatherproof IP67 rated enclosure certified to SAE J1171 ignition protection standards, the 7183 is safe for installation in engine compartments, battery spaces, and exposed marine environments. The unit features a Type III switchable design with a high-visibility yellow reset lever and red Push-to-Trip button. Its "Trip Free" mechanism prevents the breaker from being forcibly held closed during an active overcurrent fault.

Key Features
