Product: Electric Winch Relay (Model 4255) — 12 V to 24 V What this is A heavy-duty winch relay / solenoid (model 4255) designed for 12 V–24 V electric winch systems to provide reliable switching of high load currents. Key benefits — why you need it Durability: Robustly engineered to withstand harsh winch-system environments and repeated use. Reliable switching: Silver-alloy contacts and advanced manufacturing produce stable electrical performance and good conductivity, reducing contact wear and voltage drop. Long service life: Mechanical life rated to 100,000 cycles for extended operational reliability. High current capacity: Handles a maximum load current of 300 A for demanding winch pulls. Efficient operation: Low power consumption, specified at 28–30 W, to minimize electrical draw from the vehicle or power source. Quality assured: Produced and inspected under strict production standards to ensure consistent performance. Important specifications Model: 4255 Operating voltage: 12 V–24 V Contact material: silver alloy Power consumption: 28–30 W Mechanical life: 100,000 operations Maximum load current: 300 A Dielectric strength: 660 VDC (1 s, 50 Hz) Function and compatibility Functions as the main switching relay/solenoid for electric winches that operate on 12 V or 24 V systems. Compatible with most winch systems that require a high-current relay with the above voltage and current specifications. Check physical mounting and terminal compatibility with your specific winch model before installation. Practical use scenarios Off-road recovery: Replace a worn relay in a 12 V or 24 V vehicle winch to restore dependable switching and maintain full pulling performance during recoveries. Utility and light industrial winches: Use in on-site winching equipment where frequent cycles and high currents are expected; reliable for repetitive lifting/pulling tasks. ATV/UTV and trailer winches: Provides a compact, efficient relay solution for utility vehicles and trailers that draw from 12 V or 24 V systems and require up to 300 A switching capacity. Installation and maintenance notes Verify voltage and terminal fit before installation; secure wiring and mounting to prevent mechanical stress. Regularly inspect electrical connections and contact surfaces for corrosion or damage, especially in harsh or wet environments, to maintain conductivity and performance. Replace with model 4255 to keep consistent performance and compatibility when original relay is damaged or worn. What it stands out for Combines silver-alloy contacts, a long rated mechanical life, and a 300 A load capacity in a relay designed specifically for 12 V–24 V winch applications, manufactured under strict quality controls for dependable operation.
