Siemens 3TH4244-0AK6 is an 8-contact SIRIUS control relay (contactor) with four normally open and four normally closed auxiliary contacts and a 120 VAC coil, designed for EN 50011 control circuits. It uses screw-terminal connections for both the coil and auxiliary contacts, making it suitable for compact control panels in automation environments. The coil is rated for 120 VAC at 60 Hz (with 110 VAC/50 Hz variants listed in catalogs), and the device is identified as 44E within the 3TH4 family. This configuration supports multiple signaling and interlock paths from a single device, helping streamline panel wiring in machine control and OEM applications.
