Contactor working principle When the contactor coil is energized, the coil current will generate a magnetic field. The generated magnetic field causes the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the AC contactor to act. The normally closed contact is disconnected and the normally open contact is closed. Both they are linked. When the coil is de-energized, the electromagnetic attraction force disappears, and the armature is released under

Single Phase Contactor - Connections Explained, Application plus the Current in the Coil and Load Matt and Joe show how a single phase contactor can be controlled by a 1 way switch and be used to turn on many heavy current drawing loads. We see how many lighting points say in a factory can be turned on by a simple light switch via a contactor.
