Definite Purpose Contactors are electrically operated switching devices specifically designed for the heating, ventilation, air conditioning and refrigeration (HVAC) industries. Typically, they are controlled by automatic thermostats or by manual pushbutton devices. These are commonly found in applications including pools, pumps, compressors, elevators, lighting, cranes, hoists, vending machines, battery chargers and a host of other appliances. They have UNIVERSAL MOUNTING PLATES which allow interchangeability between competing brands and eliminates the need for changing hole patterns when doing replacements. 20-40A have common footprints and 60-75A have common footprints.
