The Siemens 3TX74023RY2 is a replacement coil module used in Siemens 3TX series contactor systems. It is designed to restore the electromagnetic operation of compatible contactors by replacing the original coil unit. This ensures reliable switching performance, proper pull-in/drop-out action, and long service life in industrial control applications.
It is typically used in Siemens 3TX / 3TF / 3TH series contactors, depending on frame size and coil voltage class. The coil is an essential spare part for maintenance, allowing contactors to be repaired without replacing the full unit.
From Siemens coil coding, “RY2” represents a specific coil execution variant, usually linked to a defined AC/DC coil voltage range and suppression configuration used in industrial automation systems.
