Siemens 110V AC Magnet Coil for 3TF44 / 3TF45 / 3TF46 / 3TF47 Contactors | 3TY7443-0AF0

🔹 Siemens Magnet Coil – 3TY7443-0AF0 (110V AC, for 3TF44 / 3TF45 / 3TF46 / 3TF47 Contactors)

🔹 Product Description

The Siemens 3TY7443-0AF0 is a 110V AC magnet coil designed for Siemens 3TF44, 3TF45, 3TF46, and 3TF47 power contactors. It provides the electromagnetic force required to operate the contactor mechanism, ensuring reliable switching of motors and electrical loads in industrial control applications.

When energized with 110V AC, the coil generates a magnetic field that attracts the contactor armature, closing the main contacts and allowing power flow to the connected load. When de-energized, the contactor returns to its normal state through the spring-return mechanism.

This replacement coil is commonly used in motor control centers (MCCs), industrial automation panels, machinery, pumps, compressors, HVAC systems, and power distribution applications where dependable contactor operation is essential.
