The preferred successor is 3RT2926-1CB00, which drops into the same S0 footprint and covers the same voltage range. For new builds or BOM updates, the successor is the recommended path. For existing installations needing a like-for-like spare, the 3RT1926-1CB00 is still sourced through independent distribution against an RFQ. ## Temperature limits and compliance baseline RoHS compliance date is marked as 07/01/2006 — the part meets the original EU RoHS deadline.","metaTitle":"Siemens 3RT1926-1CB00 SIRIUS Surge Suppressor, RC Element","metaDescription":"Siemens 3RT1926-1CB00 SIRIUS RC surge suppressor for S0 contactors. 24-48 V AC / 24-70 V DC.
