Review on 🔌 5-Pack Waterproof Relay Harness - 40/30 AMP 12V DC, Heavy-Duty 12 AWG Tinned Copper Wires, 5-PIN SPDT Bosch Style Automotive Relay by Freddy Hammonds

People with burning relays please ensure you make solid connections (especially on the load leads) also if you are replacing an existing burnt relay there is a chance that the load, be it a Fan or something else, is drawing too many amps, check the load connection, it's probably burned and melted (this will generate a lot of heat over time and destroy your relays, or look for a loose or bad ground on the load. Read Seeing the specifications in the product description, this relay operates on less than 14 volts and draws only 1.8 watts to drive the coil, which is approximately 15% of 1 full amp at a nominal 12 volt with the engine off and 13% of 1 full amp with the engine running Motor corresponds to motor, let's say 13.5 volts plus or minus with charging via the alternator, that's nothing, ü never exceed its limits, I always try to stay 10-15% lower than calculated, also 40 amps is a LOT! I wouldn't use this relay to power a 40 amp accessory, for that I would use something like a starter motor or snow plow solenoid with good pure copper wiring. avoidance. Only time will tell how durable these relays are when wired properly.
