widely used for the switching of motors, capacitors (for power factor correction) and lights. As the name indicates it is used to make or break contacts as like an ordinary on-off switch. The only difference is that the contactors have an electromagnet that holds the contacts when energized whereas switches do not have it. The basic operation of a contactors is similar to that of a relay but their contacts can carry much more current than relays. Relays cannot be directly used in circuits where the current exceeds 20 amperes. In such conditions, contactors can be used. They are available in a wide range of ratings and forms. Also, they are available up to the ampere rating of 12500A. They cannot provide short circuit protection but can only make or break contacts when excited.
