Function & Application

The magnetic coil is the core actuating element of a contactor. Its function is to convert electrical energy into mechanical movement:

1. Energization: When the control voltage ($42\text{ V AC},50\text{ Hz}$) is applied to the 3RT2934-5AD01 coil, it generates a magnetic field.
2. Actuation: This magnetic field pulls the armature, which closes or opens the main contactor poles, thereby connecting or disconnecting the load (e.g., a motor) from the main power supply.
3. Application: Primarily used as a replacement or spare part for the control circuits of 3RT2.3 power contactors in motor control centers, machinery, and industrial automation systems requiring a $42\text{ V AC}$ control signal.
