🔹 Siemens Magnet Coil – 3TY7443-0AB0 (24V AC, for 3TF44 / 3TF45 / 3TF46 / 3TF47 Contactors)
The Siemens 3TY7443-0AB0 is a 24V AC magnet coil designed for Siemens 3TF44, 3TF45, 3TF46, and 3TF47 power contactors. It provides the electromagnetic force required to operate the contactor, enabling reliable switching of motors and electrical loads in industrial control systems.
When energized with 24V AC, the coil generates a magnetic field that pulls the contactor armature, closing the main contacts. Upon de-energization, the contactor returns to its normal state through the spring mechanism, ensuring safe and dependable operation.
This replacement coil is commonly used in motor control centers (MCC), automation panels, machinery control systems, pumps, compressors, and industrial power distribution applications.
