The Blue Sea Systems 285-Series 40A panel mount circuit breaker (Model: 7082-BSS) is a great choice. 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. It meets SAE J1171 external ignition protection requirements and is weather resistant. This unit combines switching and circuit breaker functions, 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 include 40A amperage, 48V DC maximum voltage, surface mounting, a thermally responsive bi-metal blade, 60 in-lb (6.78 Nm) terminal stud torque, 3000A interrupt capacity at 48V, an operating temperature range from -40°C to 85°C, Type III circuit breaker class, and an M6 terminal stud that accepts 1/4' ring terminals.
Using this Blue Sea 285-Series circuit breaker is easy. Just mount it on the surface as it's designed for surface mounting. When there's an issue with the circuit, the breaker will trip and the visible reset lever will show the open condition. To reset it, simply use the lever. However, don't use it as a switch in situations where high inrush currents are expected. For maintenance, keep it clean and dry as it's weather resistant but still needs basic care. Check the terminal stud torque regularly to ensure proper connection. Make sure it operates within the temperature range of -40°C to 85°C. If you notice any abnormal behavior, stop using it and consult a professional.
