Blue Sea Systems 7184 285-Series Thermal Circuit Breaker – 60A, 48V DC, Surface Mount

Meet the Blue Sea Systems 7184 285-Series Thermal Circuit Breaker—an all-in-one solution that blends circuit protection with a built-in switch, designed for rugged marine DC networks. With a 60A rating at 48V DC, this surface-mount unit is a practical choice for windlasses, electric winches, and other demanding loads on boats.

A prominent, visible lever shows when the breaker has tripped, offering quick status checks during busy voyages. The Trip-Free design ensures the switch cannot be held in the ON position when a fault is detected, helping to prevent prolonged arcing or unintended energizing of the circuit. The device is ignition protected and water resistant, broadening its installation options from engine rooms to exposed areas, making it suitable for gasoline-powered boats and other demanding environments.
