About this item

  • 【Two Models】: There are 4-pin and 5-pin available, please purchase them according to your needs. 4-pin model is JD2912-1H-12VDC 40A 14VDC, 5-pin model is JD2912-1Z-12VDC 40A 14VDC. They are responsive, with start-up time≤10ms, release time≤5ms, and excellent working performance.
  • 【Practical Feature】: The relay controls the high voltage line current by controlling the low voltage line current and acts as a current switch. It is mainly used in automobiles to start the motor rotation by controlling the high current through the small current, so as to drive the magneto rotor inside the generator to rotate.
  • 【Safe & Reliable】: The relay is well sealed, which is waterproof and dustproof to better protect the internal components. The plastic shell is insulated and flame retardant, so it's safer and will not easily fail or short circuit. The brass pins and silver contacts have good electrical and thermal conductivity.
  • 【Quantity & Installation】: You will receive 2 relays measuring 2.05×1.13 inches. They are compact and portable enough to fit in a toolbox without taking up much space. You only need to connect the relays with wires without any other tools, so you can easily use and replace them to make your car parts work properly.
  • 【Widely Used】: Its working voltage is 12V DC, which suits for cars, motorcycles, ships and more. The high coil capacity of 40A can easily cope with high current. It is broadly applied to install electric cooling fans, electric fuel pumps, electric water pumps, luggage compartment solenoid valves, horns and so on.

I used these povtii 40A relays to replace some questionable relays for my electric fans on my truck. They have worked well and I have had no issues so far. These are way cheaper than buying them at the parts store. Good buy!

I picked these up to use with a cold plate I had built while working on some projects. I used the 5 pin relays as I was not originally sure if I wanted normally open or closed until I got further into my final design.I am very happy the the current handling via the relay. The cooling plate will peek 32amps at 13.6 volts but typically idles much lower. The relay is holding up very well with the cycling of the power as it tries to hold temperature on the plate.
