Be carefull to check the contactor coil pull in voltage
I bought two of these for some AC units at work. The picture shows the 48VAC model but I ended up with the 208VAC model. I simply did not pay attention to the title and instead focused in on the products model number in the sample picture. My fault in a way but since there are no options on the item page to select different coil voltage models I think it's bad form for them to use the picture of the most common model when they should use the picture of the one they are selling.
