HELLA H41773001 Solid State Ceramic 32 Amp SPST Mini Relay

Did the job

I used two of these to wire-up a high amperage, PWM (pulse width modulated) engine cooling fan, and I am very pleased with there performance. Amperage rating for this relay is 22 amps, at maximum operating temperature, according to Hella's web site. Use multiple relays, wired in parallel, to match your equipment's maximum operating amperage + 15%. My fan pulls 35 amps, so I used two relays for a total of 44 amps. (35 amps + 15% = 40.25 amps) This relay will fit in a standard socket, and the pins are numbered the same as a standard relay, but the wiring is different. 30 = Battery + (High Amperage) 87 = Load (High Amperage) 85 = Ground (Low Amperage) 86 = Switched Ground (Low Amperage)

This relay is perfect for variable speed output control. The pinout is different than standard Bosch relay so it is not plug and play. I have gotten 3 of these now and they all have shuffle wear on the body of the relay but the electrical terminals are unmarked.

Bought these relays, did not wire my ECU correctly and thought the issue was these relays, the issue was caused by not adding a power to Pin A26 on my Haltech Elite ECU, these relays would have worked great and would have been reliable, unfortunately I returned them.

Works perfectly
