A contactor is an electromechanical device used to switch an electrical circuit on or off. It's commonly used in control circuits for motors, lighting, heating, and other electrical loads. Contactors use an electromagnetic coil to control the opening and closing of electrical contacts to manage the flow of electricity in a circuit. A contactor typically consists of several key components: 1. Coil: The coil is an electromagnet that, when energized, generates a magnetic field to pull in the contacts, closing the circuit. Contact of coil in the contactor named A1 and A2 2. Contacts : These are the points where the electrical circuit is either connected or disconnected. Contacts can be made of various materials, like silver, and are designed to handle specific voltage and current ratings. Normlly close (NC) and Normally Open (NO) 3. Enclosure: This is the housing that protects the internal components of the contactor, shielding them from environmental factors and ensuring safety. 4.
