🔹 Siemens Magnet Coil – 3TY7443-0AU0 (240V AC, for 3TF44 / 3TF45 / 3TF46 / 3TF47 Contactors)
The Siemens 3TY7443-0AU0 is a 240V 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 dependable switching of motors and electrical loads in industrial control systems.
When energized with 240V AC, the coil creates a magnetic field that pulls the contactor armature, closing the main contacts and allowing power transmission to connected equipment. Upon de-energization, the contactor returns to its normal position through the spring-return mechanism, ensuring safe operation.
This replacement coil is widely used in motor control centers (MCCs), industrial automation panels, HVAC systems, pumps, compressors, conveyors, and power distribution applications, where reliable contactor performance is essential.
