KanSmart winch solenoid relay 12V 250A — direct-fit weatherproof replacement for 3,000–5,000 lb ATV/UTV winches

KanSmart 12V 250A winch solenoid relay contactor: a direct-fit, weatherproof replacement that routes high-current power for ATV and UTV winches rated roughly 3,000–5,000 pounds.

If your winch switch responds but the motor won’t turn, or a burned contactor has left you stranded, this KanSmart solenoid relay is built to restore reliable power distribution. Constructed from corrosion-resistant steel with a powder-coated finish and factory-tested before shipment, the unit is intended as a like-for-like swap for many common winch systems and OEM reference part numbers.

Will this KanSmart solenoid fit my winch model?

The relay is designed to be compatible with a broad range of ATV and UTV winches and lists common reference part numbers used by several manufacturers. It targets applications that require a 12V, 250A contactor for winch motors in the approximate 3,000–5,000 lb capacity range. Always compare mounting points, terminal layout, and reference part numbers to confirm fit before ordering.

• Matches several WARN reference numbers and many aftermarket winches
• 12V, 250 amp continuous capacity suitable for mid-range winches
• Compare physical mounting and terminal positions before installation
• Works with winch brands such as Polaris, Honda, KFI, Ramsey, Superwinch, and others

How durable and weather-resistant is this winch relay?

KanSmart built the relay from solid steel and applied a protective powder-coat to resist rust and abrasion in wet or muddy conditions. The design includes protective caps for the main terminals and a sealed coil area to reduce moisture intrusion, helping maintain reliable switching outdoors.

• Powder-coated steel housing for corrosion resistance
• Terminal caps included to shield connections from dirt and water
• Factory-tested units shipped to ensure proper function on arrival
• Meant for exterior vehicle use under typical off-road conditions

How does installation work and what wiring is required?

Installation is straightforward for anyone comfortable with basic vehicle wiring and bolt-on replacements. The package includes a wiring diagram and labeled wires; green and black control the in/out switch, black and red connect to the battery, and blue and yellow run to the winch motor. Secure battery connections and insulated fasteners are recommended for safe operation.

• Includes installation instruction and six protective terminal caps
• Green and black = switch control (in/out)
• Black and red = battery connections; blue and yellow = motor outputs
• One-year warranty for replacement if defects occur

What practical benefits does this relay deliver on the trail?

Replacing a faulty solenoid restores predictable power routing so your winch responds reliably to switch commands and reduces electrical stress on other components. The contactor simplifies control by handling higher currents centrally, protecting smaller switch wiring and improving overall system longevity when installed correctly.

• Prevents switch overload by centralizing high-current switching
• Improves winch responsiveness and reduces intermittent failures
• Protects vehicle wiring from excessive current draw and heat
• Replaces worn contactors without the need to replace the entire winch

Who is this for? The KanSmart 12V 250A winch solenoid relay is intended for ATV and UTV owners, mechanics, and outdoor enthusiasts who need a robust, drop-in replacement for a failed contactor. If you run mid-range winches from Polaris, Honda, Warn-compatible systems, or common aftermarket brands and want a weather-resistant, tested relay with clear wiring guidance and a one-year warranty, this unit is engineered to get you back to work or play quickly and reliably.
