Product features
Weather-Resistant Housing
Built with durable ABS plastic or metal, many boxes are sealed to IP55 standards or higher, protecting internal components against water, mud, snow, and dust, essential for off-road conditions.
Pre-Wired & Easy Setup
Designed with pre-cutting mounting brackets and pre-wired cables, these boxes offer "plug-and-play" installation for most ATV, UTV, and SUV winches.
Heavy-Duty Contactor/Solenoid
Contains a 12V/24V DC solenoid (commonly 250A to 500A) to handle high electrical loads during heavy pulling, often featuring corrosion-resistant contacts.
Remote Control Compatibility
Features built-in sockets for wired remotes and receivers for wireless, sometimes allowing multiple remotes, enabling safe, long-distance operation away from the winch line.
Safety and Protection Features
Include features like auto-shutoff remotes to save battery, and some advanced units have thermal protection to stop the motor during excessive heat or low voltage.
Universal Compatibility
Designed to fit a wide range of electric winch capacities, most commonly between 2,000 lbs to 17,000 lbs, making them suitable for various vehicles and recovery needs.
Kit Components & Design
500A Solenoid Relay
The core of the system is a DC12V solenoid relay housed in a compact, heat - dissipating black casing. It features four copper terminals for secure power connections and two control terminals, ensuring reliable current switching for winch motor engagement.
Dual Wireless Remotes
Two compact, blue - hued remotes offer redundant control. Each remote has four buttons: "UP"/"DOWN" for winch direction (retracting or deploying cable) and "ON"/"OFF" for power activation. A prominent orange "WARNING" label advises users to disconnect power when not in use, enhancing safety.
Wired Control Box
The black control box, marked with a serial label, acts as the brains of the operation. It processes signals from the remotes and activates the relay. Color - coded wires (blue, yellow, red, black) simplify installation, connecting to the vehicle's battery, winch motor, and ignition.
