The Siemens 3TY7443-0XR1 is a genuine spare part coil designed for the Sirius 3TF34-35 and 3TF44-45 series contactors. Engineered for reliability and seamless integration, this coil ensures the consistent performance of your industrial control systems. It is a critical component for maintaining and repairing your existing contactors, preventing costly downtime and extending the lifespan of your equipment. This coil operates on a standard AC supply with a rating of 440V at 60Hz and 367V at 50Hz, making it a versatile and dependable solution for various industrial applications.
The contactor coil is the electromechanical core of a contactor. When voltage is applied to the coil, it generates a magnetic field. This magnetic field attracts an armature, which in turn causes the main contacts of the contactor to close or open. In the case of the Siemens 3TY7443-0XR1, it functions as the actuator for the 3TF34-35 and 3TF44-45 contactors, enabling the controlled switching of electrical circuits. Its precise voltage rating ensures that the magnetic field is strong enough to operate the contactor reliably under specified conditions.
