Electric Components
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 control box, one circuit 
breaker, and two analog switches or one Digital System 
Switch. All new electric Radial, Performa, and captive 
winches are supplied with the appropriate dual-function 
control box. For replacement or retrofit control boxes, 
contact Harken.
Hydraulic winches require two analog switches or one Digital 
System Switch. 
Analog Switches
Harken offers simple, waterproof switches for electric and 
hydraulic winches. Order two switches for each winch.
High-Amperage Circuit Breakers
Harken offers four panel-mount, high-amperage circuit 
breakers. They are compact, waterproof, weather-resistant, 
and ignition-protected. Circuit breakers are available for 
12-, 24-, or 48-volt DC systems.
Dual-Function Control Boxes
This labor-saving control box with built-in load controller 
combines two products into one, reducing wiring and 
connection points by almost half, greatly simplifying 
installation of Harken electric winches. Supports Digital 
System Switch or analog switches. A mix of switches 
is not supported.
