The Blue Sea Systems 7144 187-Series thermal circuit breaker is designed for reliable circuit protection and switching in demanding marine environments. With a 100 Amp rating, this device seamlessly combines circuit interruption and manual reset functionality into a durable, compact package. Its thermally responsive bi-metal blade ensures precise trip responses, providing safety and peace of mind during operation. Constructed with a thermoset polyester case, the breaker offers excellent durability and resistance to harsh conditions. The waterproof design and recessed mounting holes deliver a clean appearance and secure installation, making it ideal for marine and other rugged applications. The large, vertically or horizontally oriented lever allows for quick trip status identification and easy operation, even in tight spaces. Heavy gauge wire lugs with large terminal clearance facilitate high torque connections, ensuring reliable electrical contact. All components meet SAE J1171 external ignition protection standards, making it safe for installation aboard gasoline-powered boats, and the device's trip-free design prevents holding the switch in the ON position during fault conditions. Operating within a temperature range from -25°C to +82°C, the circuit breaker maintains consistent performance across diverse environments. Its high interrupt ratings at various voltages ensure it can protect circuits effectively against overloads and short circuits. Whether used in marine, RV, or industrial settings, this circuit breaker combines safety, durability, and ease of use in a single, high-quality component.
