For a Definite Purposed Contactor, like the one you may have, look how many poles, inductive amp and coil voltage. If you don't know, look the label on your contactor this information is there. You may have a 1+ pole, 40 amp (inductive), 24 Volt coil. I know because for this size the unit it's what you usually have. Get the information look the Grainger catalog page 334, if you see one similar and call Grainger. Do NOT install a contactor with less amp that the one you have. There is not a rule to how cross reference for a contactor, I'm doing HVAC & R for 15 years.
