What it is: One 12 V winch relay kit containing 1 relay and 1 connecting wire, rated for 250 A and designed to work with winches up to 12,000 lb. Why you need it: Replaces weak or unreliable relays with a purpose-built unit that provides fast, consistent power to your winch motor, reducing hesitation and electrical stress during heavy pulls. Key benefits: Reliable high-current switching: 250 A rating ensures the relay can handle heavy loads without excessive heating or voltage drop. Fast activation: Internal brass coil and high-conductivity design provide quick motor start and steady current flow when you engage the winch. Durable construction: Robust, corrosion-resistant housing made with AB material protects internal components for long service life in demanding conditions. Simple installation: Kit includes the relay and a connecting wire to integrate with existing 12 V winch systems. Performance note: Designed for intermittent heavy use. For optimal performance and longevity allow a 20–30 second cooling interval between extended pulls. Compatibility and function: Electrical: 12 V systems only, 250 A continuous/heavy-duty switching capacity. Intended to act as the primary switching relay for electric winches, ensuring clean, reliable power delivery to the motor. Material: corrosion-resistant outer housing constructed from AB material (as specified). Typical use scenarios: 1. Off-road vehicle recovery: Replace a worn relay to ensure your 12 V winch reacts instantly during vehicle recovery and heavy pulls up to 12,000 lb. 2. Work trucks and trailers: Use on utility or towing vehicles that require dependable winch operation for loading and unloading heavy equipment. 3. Agricultural or light industrial hoisting: Install on portable winch setups to improve starting performance and reduce relay wear during repeated tasks. What’s included: 1 relay, 1 connecting wire. No modifications to the winch required beyond standard relay wiring. Practical reminder: Confirm your winch motor and wiring are compatible with a 250 A relay and follow proper fuse and wiring practices for safety and optimal performance.
