What is a contactor?

Contactor is used for switching motor systems. It has an important role in providing energy transportation from one point to another. Thanks to this system, when excessive current occurs, the mechanism on which it is located does not shut down. Fuses used in homes and workplaces can turn themselves off when excessive current occurs. The contactor does not have such a feature.

Contactors, which are not sensitive to overcurrents, cannot be used alone. Contactors; It must be used together with parts such as thermal relay, fuse and motor protection switch. When excessive current occurs, these parts can easily stop the current. When used alone for contacting, high currents may damage the motor.
