Blue Sea Systems presents the 285-Series 150A panel-mounted circuit breaker (Model: 7089-BSS). It's a direct replacement for 185-Series circuit breakers. The visible reset lever clearly shows the open condition. This breaker is ignition protected, making it safe for gasoline-powered boats. It meets SAE J1171 external ignition protection standards and is weather-resistant. It combines switching and circuit breaker functions in one unit, but don't use it as a switch for high inrush currents. It has a 'Trip Free' feature, so it can't be held closed after tripping. Specifications include 150A 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 the Blue Sea 285-Series 150 Amp Circuit Breaker is straightforward. First, make sure to mount it on a flat surface. The breaker can handle up to 150A and 48V DC, so ensure your electrical system is within these limits. When the breaker trips, the visible reset lever will show the open condition. Simply reset it to restore power. Remember, don't use it as a switch in situations with high inrush currents. For maintenance, keep it clean and dry. Check the terminal studs regularly and tighten them if needed to maintain the 60 in-lb (6.78 Nm) torque. It can operate in temperatures from -40°C to 85°C, but avoid exposing it to extreme conditions for long periods. If you notice any unusual behavior, it might be time to replace the breaker.
