A contactor has three components. This article can give you a clear picture of the difference between relays and contactors. The Basics of Contactors Contactors are useful in commercial and industrial applications, particularly for controlling large lighting loads and motors. Contactor: The main function of the contactor is to control the electric current to the motor. 19. Welcome to this EATON’s guide, which is about starters, devices that control the use of electrical power to equipment, usually a motor. It is considered to be a special type of relay. Maintenance. As the name implies, starters “start” motors. stream Simplified Schematic Of Main Electric Power Generation | pdf. Constructional Features: Contactors and relays have similar construction.
