🔹 Replacement Coil – Siemens 3TX74623JY1 (3TX Series)
The Siemens 3TX74623JY1 is a replacement coil module used in Siemens 3TX series contactor systems. It is designed to restore the electromagnetic operation of compatible contactors, ensuring reliable switching performance, proper pull-in and drop-out action, and long service life in industrial control applications.
This coil is part of the Siemens 3TX7402 / 3TX7462 accessory coil family, typically used with Siemens 3TF / 3TH / 3TC / 3TB contactors depending on frame size and configuration. It is widely used in control panels, MCCs, and automation systems for maintenance and repair purposes without replacing the full contactor assembly.
From Siemens coding practice, “JY1” indicates a specific coil execution variant, generally associated with a defined AC/DC coil voltage class (often mid-voltage industrial range) and suppression/protection configuration, ensuring stable energizing and reduced coil switching stress in industrial environments.
Coil-related accessories in the 3TX7402/3TX7462 family are also used alongside surge suppression modules (varistor/RC elements) to improve contactor reliability and lifespan in switching circuits.
