Air Conditioner Contactor Issue

6 years ago

last modified: 6 years ago

I am switching out my old AC contactor (hn51kc024b) with a new one, however, the configuration and labeling is entirely different and I need help making sure I'm placing all the wires correctly. Anyone have some perspective as to how to place the wires on the new contactor?

The wires in going to the big screws in the old contractor pretty much go to the matching terminals on the new one.

The coil wires are (the ones on the little tabs on the right of the old one, purple on the bottom and brown black on the top) go a little different on the new one. One wire (let's say the purple one) will go to one of the tabs on the left side of the new one. The other two, go to the tabs on the right side.
