LLNSEAUTO 12V 250A Winch Solenoid Relay Kit — IP67 Sealed Contactor with Handlebar Rocker Switch for 1500–5000 lb Winches

This LLNSEAUTO 12V 250A winch solenoid relay kit is a ready-to-install electrical contactor and handlebar rocker switch set designed to control 1500–5000 lb ATV and UTV winches.

If you need a compact, IP67-sealed solenoid to route battery power to a winch motor reliably, this kit supplies the contactor, terminal caps, a handlebar-mounted rocker thumb switch and mounting hardware to replace worn components or build a custom control system. The relay handles up to 250A continuous load at 12V DC and is compatible with many common winch brands and vehicle makes.

How does this relay control my winch safely?

The LLNSEAUTO solenoid acts as a high-current electrically operated switch that isolates the winch motor from the battery until you command it. When you press the handlebar rocker switch the solenoid closes, allowing heavy current to flow through copper terminals without routing that current through the small switch contacts.

• 250A rated copper terminals for high current durability
• SPDT contact form enabling forward and reverse winch control
• ABS housing and IP67 sealing to resist dust and water ingress
• Terminal caps included to prevent accidental shorting

Will this fit my ATV or UTV and common winch brands?

The kit is built for 12V systems and supports typical winch capacities between roughly 1500 lb and 5000 lb. It’s compatible with many OEM and aftermarket systems that use a solenoid-operated contactor or relay style wiring.

• Works with HONDA, POLARIS, ARCTIC CAT and similar 12V vehicles
• Compatible with WARN, BADLAND, MILE MARKER, SMITTYBILT and other winches
• Terminal size 8-32 and bullet male/female connectors match common harnesses
• Includes mounting brackets and installation kit for straightforward swap-in

What are the physical and electrical specs I should know?

Key specifications let you confirm fitment and safety margin for your winch setup. Knowing these values helps ensure the relay will handle your winch’s inrush and running currents without overheating or premature failure.

• Operating voltage: 12V DC; rated current: 250A
• Contact form: SPDT for directional control; terminal size: 8-32
• Materials: ABS case, copper terminals; IP67 sealing rating
• Wire connector type: bullet male and female included in kit

What’s included and how easy is installation?

The kit contains the core components to replace a worn solenoid and add a handlebar control. Basic hand tools and standard wiring practices are all that’s required; a wiring diagram and the included mounting hardware speed the process.

• 1x 12V 250A winch solenoid relay contactor with terminal caps
• 1x handlebar rocker thumb switch with mounting bracket
• Installation kit: mounting brackets, screws, and bullet connectors
• Fits standard 8-32 terminal connections—no special crimpers needed

Who is this for: This LLNSEAUTO kit is aimed at ATV and UTV owners, mechanics and fabricators who need a durable, serviceable solenoid and handlebar switch for 12V winch systems. It’s ideal for replacing failed contactors, upgrading older relays to a sealed IP67 design, or building a tidy handlebar-mounted control solution for recreational and utility vehicles using winches in the 1500–5000 lb range.
