🔹 Magnet Coil for Contactor – Siemens 3TY48030BD4 (3TY Series)
The Siemens 3TY48030BD4 is a magnet coil for contactors from the Siemens 3TY series, designed to provide electromagnetic actuation for Siemens industrial contactors. It is used to energize the contactor mechanism, enabling reliable switching of electrical circuits in motor control and automation systems.
When the coil is energized, it generates a magnetic field that pulls the contactor armature, closing the main contacts. When de-energized, the spring mechanism returns the contacts to their original state, ensuring safe and controlled switching.
This coil is typically used in Siemens 3TF / 3TH / 3TB series contactors, depending on frame size, and is commonly installed in control panels, MCCs, and industrial automation systems.
From Siemens accessory references, the 3TY48030BD4 variant is commonly associated with a 42V DC coil execution, used in specific control voltage applications requiring safe low-voltage operation.
