A Relay Contactor used in an electromechanical device is responsible for establishing and interrupting the power supply. It consists of a set of contacts, made of conductive material, housed within a robust enclosure. When the control circuit energizes the coil inside the contactor, it generates a magnetic field, attracting the contacts to close and complete the electrical circuit.Attributes:• Preventing direct user interaction with high-voltage circuits• Enables features such as remote motor activation and deactivationApplications:A Relay Contactor often incorporates auxiliary contacts for signaling and monitoring purposes, enhancing the overall safety and functionality.
