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.","metaTitle":"Siemens 3RT1944-5BE41 SIRIUS Magnet Coil, 60 V DC, Size S3","metaDescription":"Siemens SIRIUS 3RT1944-5BE41 magnet coil for Size S3 contactors, 60 V DC screw terminal.
