The Siemens SIRIUS 3RT1926-1CD00-ZX90 is an RC-type surge suppressor designed for direct mounting onto Size S00 contactors. It covers a supply range of 127 to 240 V AC and 150 to 250 V DC, making it suitable for suppressing switching transients across the coil of the contactor it mounts to.
This part is flagged as a phased-out product. The official successor is the SIRIUS 3RT2 series suppressor.
