Function
The magnetic coil, or electromagnet, is the heart of a contactor’s operation. When a 220 V AC voltage is applied to the Siemens 3RT2944-5AN21 coil, it generates a magnetic field. This field pulls the armature, which in turn closes the main contacts of the 3RT2.4 contactor. This action allows electrical current to flow to the connected load, such as a motor or heating element.
When the voltage is removed, the magnetic field collapses, and a spring pushes the armature back, opening the contacts and interrupting the circuit. This makes it a critical component for controlling power in various automation applications.
