QWORK 12V 250A Solenoid Relay for ATV/UTV Winch 3000–5000 lb — Silver-Alloy Contacts

QWORK Solenoid Relay is a 12V replacement contactor rated for 250A continuous (350A peak) designed to operate 3000–5000 lb ATV and UTV winches.

This heavy-duty replacement solenoid relay provides the electrical switching needed to control medium-capacity winches on ATVs and UTVs. Built with silver-alloy steel contact points and a standardized terminal layout, it simplifies swaps for worn or damaged relays and restores reliable current flow while reducing contact resistance. Before installation, confirm the relay’s size and terminal positions match your winch control box to ensure a direct fit.

How much current can this QWORK relay handle?

The relay is engineered for 12V DC systems and supports sustained currents up to 250 amps, with brief peaks up to 350 amps for heavy pull starts. This rating matches the electrical demands of many 3000–5000 lb winches without overheating under normal use.

• Continuous rating: 250A at 12V DC
• Short peak capability: up to 350A for brief bursts
• Silver-alloy contactors for low resistance and improved conductivity
• Suitable for high-load motor engagement during winch pulls

Will the relay fit my ATV or UTV winch control box?

Compatibility is generally good for 3000–5000 lb winches, but the physical dimensions and terminal arrangement must match your existing relay to avoid wiring or mounting issues. Verify measurements and terminal spacing against your original part to guarantee a bolt-in replacement.

• Designed for medium-capacity winches (3000–5000 lbs)
• Standard terminal layout for common winch controllers
• Check mounting hole pattern and relay thickness before purchase
• Compare terminal type (threaded posts versus spade) with your harness

What materials and construction improve performance?

QWORK uses internal silver-alloy steel contactors that lower electrical resistance and resist arcing, which helps maintain reliable conductivity over many cycles. The outer casing is finished in black and built for secure connections inside a control box, though it should be kept free from direct moisture exposure.

• Silver-alloy contactors for enhanced conductivity and durability
• Sturdy housing with smooth black finish for easy cleaning and fitting
• Robust terminals designed for secure, low-resistance connections
• Engineered for repeated engagement under load

How should I install and maintain this winch relay?

Install the relay on a flat surface inside the control box and tighten terminals to manufacturer torque specs for safe operation. Keep the relay sheltered from water and excessive vibration to extend service life; periodic inspection of terminal tightness and corrosion will prevent electrical issues.

• Mount on a flat, secure surface inside control housing
• Use correct terminal hardware and torque settings
• Avoid direct exposure to moisture; seal or gasket the control box if needed
• Inspect terminals periodically and clean any corrosion

Who this is for: Installers, ATV/UTV owners, and repair shops needing a reliable replacement solenoid for mid-range winches will find this QWORK relay suitable. It’s best for users who can verify physical fit and wiring compatibility and who want a durable contactor with improved conductivity for heavy-duty winching applications.
