Since I ran all new wiring for my dual pump setup I went to a MSD SSR and since it has 4 ports I also wired my dual fan setup in to it. It cut down on a lot of extra wiring and it works great.Yes , and after being in the automation electrical field for 39 years , I'm surprised that more solid state relays are not used for higher current applications like fuel pumps & cooling fans . No moving parts , no contacts to burn . We us them in many high current / high cycling applications like mold machine heat control , bulk plastic dryers .
