Blue Sea 7543 C-Series Flat Rocker Circuit Breaker - Single Pole - 20A

The Blue Sea Systems 7543 is a single-pole C-Series flat rocker circuit breaker rated for 20A AC and 20A DC service. It combines circuit switching with overcurrent protection for marine electrical loads such as inverters, bow thrusters and windlasses.

The flat rocker sits flush when switched on, while the colored actuator shows when the breaker is off. Its trip-free magnetic hydraulic design cannot be held closed after tripping, and it is ignition protected for installation on gasoline powered boats.
