Blue Sea 285-Series 70 Amp Circuit Breaker Surface Mount

The Blue Sea Systems 285-Series 70A surface mount circuit breaker is a great choice. Model 7185-BSS. It can directly replace 185-Series circuit breakers. The visible reset lever clearly shows the open condition. It's ignition protected, making it safe for gasoline-powered boats and meeting SAE J1171 external ignition protection requirements. It's weather-resistant. This breaker combines switching and circuit breaker functions in one unit (but don't use it as a switch for high inrush currents). It's 'Trip Free', meaning it can't be held closed after tripping. Specifications: 70A amperage, 48V DC maximum voltage, surface mount, thermally responsive bi-metal blade, 50 in-lb (5.65 Nm) terminal stud torque, 3000A @ 48V interrupt capacity, -40°C minimum operating temperature, 85°C maximum operating temperature, Type III - switchable/manual reset - trip free circuit breaker class, and M6 terminal stud (accepts 1/4' ring terminal).

Using this Blue Sea circuit breaker is easy. First, make sure to mount it on a flat surface as it's a surface-mounted device. Connect the wires to the M6 terminal stud and tighten it to the recommended 50 in-lb (5.65 Nm) torque. The breaker will automatically trip when there's an overload or short - circuit. When it trips, you can see the reset lever indicating the open condition. Just reset it manually to get it working again. Remember, don't use it as a switch in situations where high inrush currents are expected. To maintain it, keep it clean and dry as it's weather - resistant but still needs proper care. Check it regularly, especially if it's installed on a boat. If you notice any signs of damage or abnormal operation, replace it right away. Also, make sure the operating temperature stays between -40°C and 85°C for proper functioning.
