In HVAC applications, DP contactors can be grouped into two main categories. Compact 1- and 2-pole DP contactors are the popular choice for central A/C units that are commonly found in homes. Standard frame DP contactors are primarily used in commercial and industrial units. These are mounted on the rooftops of industrial plants, hotels, hospitals, office buildings, and similar buildings. The A/C units carry ratings that range from a few tons to 500 tons.
