🔹 Siemens Magnet Coil – 3TY7503-0AR0 (415V AC, for 3TF50 / 3TF51 Contactors)
The Siemens 3TY7503-0AR0 is a 415V AC magnet coil designed for Siemens 3TF50 and 3TF51 power contactors. It provides the electromagnetic actuation required to operate the contactor mechanism, ensuring reliable switching of motors and electrical loads in industrial control and automation systems.
When energized with 415V AC, the coil generates a magnetic field that attracts the contactor armature, closing the main contacts and allowing power to flow to connected equipment. Once the control voltage is removed, the spring-return mechanism safely opens the contacts, ensuring dependable and safe operation.
This replacement coil is commonly used in motor control centers (MCCs), industrial automation panels, power distribution systems, HVAC installations, pumps, compressors, conveyors, and manufacturing facilities, where robust contactor performance is essential.
