Magnet Coil for Contactors, 3TY Series, Variant BB4 - 3TY48030BB4

🔹 Magnet Coil for Contactor – Siemens 3TY48030BB4 (3TY Series)

The Siemens 3TY48030BB4 is a magnet coil for contactors from the Siemens 3TY series, designed to provide electromagnetic actuation for industrial contactor systems. It is used to energize the contactor mechanism, enabling reliable switching of electrical circuits in motor control and automation applications.

When voltage is applied, the coil generates a magnetic field that pulls the armature of the contactor, closing the main power contacts. When de-energized, the spring mechanism returns the contacts to their original position, ensuring safe and controlled switching of electrical loads.

This coil is typically used in Siemens 3TY / compatible 3TF contactor assemblies, depending on frame size and configuration, and is commonly installed in industrial control panels, MCCs, and automation systems for motor switching applications.
