The Blue Sea Systems 7543 C-Series Flat Rocker Circuit Breaker offers reliable overcurrent protection for boat electrical systems, including inverters, bow thrusters, and windlasses. Its innovative design features a flush-mounted rocker actuator in the "ON" position, reducing the risk of accidental switching, while the color-coded actuator clearly indicates when the breaker is "OFF." This combination of switching and circuit protection into a single compact device simplifies installation and enhances system safety.
Built with a magnetic hydraulic trip mechanism, this circuit breaker is "trip free," meaning it cannot be held closed after tripping, ensuring consistent circuit protection. It is ignition protected, making it safe for installation aboard gasoline-powered boats. The breaker supports a maximum voltage of 240V AC and 48V DC, with a continuous current capacity of 20A, suitable for various marine electrical applications.
The breaker features a single pole configuration with a 1/4-20 tin-plated brass terminal stud, designed for secure connections. It has a switching cycle capacity of 10,000 cycles, ensuring durability over time. The device is rated for a torque of 35 in-lb on the terminal stud and 6 in-lb on the mounting screw, which is made from stainless steel for corrosion resistance. Its operating temperature range spans from -40°C to 85°C, allowing it to perform reliably in harsh marine environments.
Designed for easy installation, the breaker uses #6-32 stainless steel mounting screws, and its compact size makes it suitable for panel mounting in tight spaces. The unit weighs approximately 0.38 pounds, making it lightweight yet robust enough to withstand demanding marine conditions. Remember to review safety warnings, as this product contains chemicals known to cause health risks in California, and handle it with appropriate precautions.
