🔹 Replacement Coil – Siemens 3TX74023JY1 (3TX Series)
The Siemens 3TX74023JY1 is a replacement coil module used in Siemens 3TX series contactor systems. It is designed to restore or replace the electromagnetic coil function of compatible Siemens contactors, ensuring proper switching performance in industrial control panels and automation systems.
This coil is part of the 3TX7402 coil/suppression family, which is widely used in Siemens 3TF / 3TH / 3TB / 3TC series contactors depending on frame size and configuration. It ensures reliable energizing and de-energizing of the contactor for safe motor and load control.
From Siemens coil coding, “JY1” typically refers to a specific coil voltage class (commonly in the 127–240 V AC / 150–250 V DC range with suppression variant options) used in industrial control applications.
