🔹 Siemens Magnet Coil – 3TY7443-0AP0 (230V AC, for 3TF44 / 3TF45 / 3TF46 / 3TF47 Contactors)
The Siemens 3TY7443-0AP0 is a 230V AC magnet coil designed for Siemens 3TF44, 3TF45, 3TF46, and 3TF47 power contactors. It provides the electromagnetic actuation required to operate the contactor, ensuring reliable switching performance in industrial motor control and automation applications.
When energized with 230V AC, the coil generates a magnetic field that pulls the contactor armature, closing the main contacts and allowing power flow to the connected equipment. When the coil is de-energized, the spring-return mechanism safely opens the contacts.
This replacement coil is commonly used in motor control centers (MCCs), industrial automation panels, pumps, compressors, HVAC systems, conveyors, and power distribution applications, where dependable contactor operation is critical.
