Weasch Waterproof Relay Kit - 12V 40A 4-Pin SPST Automotive Relay With 12 AWG Wires

Car and marine enthusiasts, this Weasch waterproof relay is built like a tank and perfect for demanding automotive and marine applications! It's a 12V DC relay rated for 40A continuous current with a 4-pin SPST (Single Pole Single Throw) configuration. The construction is seriously heavy-duty - flame retardant housing, built-in copper coil, and silver alloy contacts that provide excellent conductivity and reliability. The wiring is quality stuff too: you get 12 AWG tinned copper wires for the main power (red wire for VDC input at pin 30 and blue wire for output at pin 87), plus 16 AWG wires for ground (yellow wire at pin 85) and trigger (white wire at pin 86). The waterproof sealing is impressive - it has a sturdy cover with sealing ring that provides excellent protection against water, dust, and moisture, so it can handle any weather conditions you throw at it. The specifications are professional-grade: rated coil voltage of 12V DC, coil power of 1.8W, coil resistance of 80Ω, and it can handle up to 27V DC operating voltage. It operates in temperatures from -40°C to +85°C, so it works in extreme conditions without issues. The relay acts as a bridge between small switches and high-powered devices, allowing you to control heavy-duty equipment with light-duty switches. Perfect for cars, trucks, boats, and any 12V system where you need reliable power switching. The package includes one complete relay with pre-wired harness, ready to install. Whether you're adding auxiliary lights, winches, compressors, or any high-current accessory, this relay provides that crucial protection for your vehicle's electrical system. The build quality feels substantially better than standard automotive relays, and the waterproof feature gives you peace of mind for outdoor and marine use. If you need a reliable, heavy-duty relay that won't let you down, this Weasch unit is definitely worth considering!
