Blue Sea 7148 - Circuit Breaker 187-Series, Surface Mount 150A

The Blue Sea 7148 Circuit Breaker 187-Series provides a reliable solution for high-amperage circuit protection, combining both switching and circuit protection functions into one compact and efficient device. This breaker offers clear, single lever operation for easy reset and troubleshooting. Its "Trip Free" design ensures the breaker cannot be held "ON" during fault current conditions, preventing potential damage to your system. Waterproof construction makes it suitable for marine environments, while recessed mounting holes give the breaker a clean, professional appearance once installed. The breaker’s large clearance around the terminal studs allows for the use of heavy gauge wire lugs, ensuring secure connections even in demanding applications.

Featuring robust 5/16 M8 terminals for high torque connections, the Blue Sea 7148 provides the strength and reliability needed in critical applications. Its large lever, which can be oriented vertically or horizontally, not only offers easy operation but also provides a clear indication of the breaker’s trip status. The breaker is ignition-protected, making it safe for installation aboard gasoline-powered boats. It also meets SAE J1171 external ignition protection requirements, adding an extra layer of safety. With a maximum voltage of 48V DC and an amperage of 150A, it’s an ideal choice for applications requiring reliable high-current protection in harsh environments.
