The Siemens 3RT1944-5BE41 is a SIRIUS magnet coil designed for Size S3 contactors. It operates on a 60 V DC control supply and terminates via screw terminals. The coil is the replacement component for the contactor's electromagnetic actuator — when the coil fails, the contactor drops out and the controlled load loses power.
This part is flagged as a phased-out product. The manufacturer lists the successor as the SIRIUS 3RT2 series.
The peer 3RT1044-1FB46 is a Size S3 power contactor with a 24 V DC coil, not a direct coil replacement. For a drop-in coil swap on an existing Size S3 contactor, the 3RT1944-5BE41 is the correct part; the 3RT2 series successor requires a contactor change.
