Blue Sea 7044 100A 187-Series Panel Mount Breaker

The Blue Sea 7044 187-Series Thermal Circuit Breaker combines switching and circuit protection into a single 100A device. It is designed for boaters who need a heavy-duty manual breaker with a clear indication of trip status at a glance.

A large lever provides vertical or horizontal position indication for instant trip status, and the trip-free design means it can't be held ON during a fault current condition. A self-trimming case eliminates the need for mounting panels or trim bezels, and the round case installs cleanly with a standard hole saw. It's fully waterproof with recessed mounting holes for a clean install, robust 5/16-inch terminals for high-torque connections, and ignition protected to SAE J1171 for safe use aboard gasoline-powered boats.
