Function

The magnetic coil is the core component that converts electrical energy into mechanical motion within a contactor. When voltage is applied to the coil’s terminals, it generates a magnetic field. This field attracts the armature, causing the main contacts of the contactor to close and allow current to flow to the load.

When the voltage is removed, the magnetic field collapses, and a spring pushes the armature back, opening the contacts and interrupting the current flow. The 3RT2934-5AK61 coil ensures this process is fast, safe, and reliable.
