The RC element absorbs the inductive kick from the contactor coil, protecting nearby PLC outputs, relays, and sensitive electronics from conducted transients. ## Lifecycle status and the direct replacement path This part is a phased-out product per the manufacturer's own description, with the official successor being the SIRIUS 3RT2926-1CC00. The preferred successor type is 3RT2926-1CC00, which shares the same Size S0 mounting footprint and RC-element design, so panel layout and wiring remain unchanged. ## Mounting and environmental fit for panel integration Designed for Size S0 contactors, this suppressor clips directly onto the contactor's coil terminals — no additional wiring or DIN-rail space needed. The AC/DC control supply voltage type means it handles both line-frequency and DC-coil contactors within the stated voltage windows.","metaTitle":"Siemens 3RT1926-1CC00 SIRIUS Surge Suppressor, RC","metaDescription":"Siemens 3RT1926-1CC00 SIRIUS surge suppressor, RC element, 48-127 V AC / 70-150 V DC, for Size S0 contactors.
