This is a universal replacement for the start capacitor heat relay and includes a surge protector. This replaces all relays on all capillary systems it also puts out a little extra voltage to the start windings to give older compressors a boost to turn over. This is an excellent replacement!
NOTE: if you need us to provide you with the correct wiring diagram to your comrpessor we must have two photos from you. One showing us the compressor and the other showing us the lugs/pins on the side of the compressor.
