5 Pack 4-PIN Relay 40/30AMP 12V DC Automotive Relays Waterproof Relay with Harness Heavy Duty 12 AWG Tinned Copper Wires (4 Pin)

Product Description This 5 Pack 4-PIN Relay with Harness is designed for demanding 12V DC automotive applications, offering reliable performance for a wide range of electrical systems. Each relay features a 40/30 AMP rating, providing robust switching capability for high-current devices such as headlights, fans, fuel pumps, horns, and auxiliary lighting. The heavy duty construction includes 12 AWG tinned copper wires, which resist corrosion and ensure efficient power transfer even in harsh conditions. The waterproof design protects the relay from moisture, dust, and debris, making it suitable for use in engine bays, off-road vehicles, marine environments, and other exposed locations. The relay operates on a Single Pole Double Throw (SPDT) configuration, allowing for both normally open and normally closed switching. With a coil voltage of 12 Volts DC and a coil resistance of 80 Ohms, it provides consistent activation with minimal power consumption at just 1.8 watts. The minimum switching voltage of 6 Volts DC ensures reliable performance in lower voltage conditions. The socket mount design allows for easy installation and secure connection, while the quick connect terminals simplify wiring. Each relay is built with copper contact material for excellent conductivity and long service life. The included harness is pre-wired with 12 AWG tinned copper wires, reducing installation time and ensuring a clean, professional finish. This 5 pack provides convenient backup or multiple unit installations for projects requiring more than one relay. Suitable for automotive, truck, RV, boat, solar, and industrial applications, this set delivers dependable switching for your electrical needs.
