Drives & Motors | Contactors (1 results found)
Contactors are devices used to start and stop motors. They include a set of contacts that open and close when the coil is energized. When contacts close, power can flow to the motor enabling the motor to operate. Unlike a manual switch, contactors can be operated remotely. This means an operator can start a motor without opening the control panel by using pushbutton controls, or a PLC can operate the contactor.
