Harken Circuit Breakers

Battery voltage and winch size determine which components you should use. For winches size B980 and above, contact Harken for appropriate components. All components sold separately. Each electric winch requires one circuit breaker. Harken offers four panel-mount, high-amperage circuit breakers. They are compact, waterproof, weather-resistant, and ignition-protected. Circuit breakers are available for 12- or 24-volt DC systems.

Stripper arm completely covers rotating winch top, preventing fingers and clothing from catching in moving parts. Adjusts to multiple positions after the winch is mounted to optimize line exit.

High-strength, lightweight
