Function

The magnet coil is the core electromagnetic component of a contactor. When energized by the 42V AC power supply, it generates a magnetic field that pulls the armature towards the core. This action closes the main contacts of the contactor, allowing power to flow to the connected load. When the power to the coil is removed, the magnetic field dissipates, and a spring forces the armature back to its original position, opening the contacts and interrupting the circuit. The 3TY7403-0AD2 ensures this switching action is executed reliably and precisely for the specified range of Siemens contactors.
