The Blue Sea Systems 7543 C-Series Flat Rocker Circuit Breaker delivers reliable overcurrent protection for marine applications such as inverters, bow thrusters, and windlasses. Its single-pole design simplifies installation and operation, providing a streamlined solution for electrical safety aboard boats. The flat rocker actuator is flush in the "ON" position to reduce accidental switching, while the color indicator clearly shows when the breaker is in the "OFF" position, ensuring easy monitoring during operation. This circuit breaker combines switching and circuit protection into a single durable device, reducing installation complexity and space requirements. Its magnetic hydraulic trip-free mechanism ensures the breaker trips during overloads or faults and cannot be held closed after a trip, enhancing safety and preventing damage to connected equipment. The breaker is ignition protected, making it suitable for installation in gasoline-powered vessels and other hazardous environments. Designed for demanding marine conditions, it can handle up to 240V AC or 48V DC and features a robust construction with stainless steel mounting screws and a tin-plated brass terminal stud for secure connections. With a switching cycle life of 10,000 cycles and an interrupt capacity of up to 5,000A at 32V DC, it offers longevity and high fault current handling capacity. Its operating temperature range from -40°C to 85°C ensures reliable performance across a broad spectrum of environments. The compact weight of just 0.38 pounds makes it suitable for space-constrained installations without compromising durability or performance. This circuit breaker provides peace of mind for boat owners seeking a safe, reliable, and easy-to-maintain electrical protection device.
