The integrated 2 NO leading auxiliary switch signals the breaker state to a PLC or status lamp without requiring a separate aux block. ## Sourcing reality — phased out, successor available This part is explicitly marked as a phased-out product. The manufacturer lists the successor as the SIRIUS 3RV2 series — the 3RV1922-1CF0 is the 3RV1-generation release. For new BOM lines or panel builds, specify the 3RV2 equivalent directly. ## Integration notes for the 3RV1 platform The release snaps onto the left side of any SIRIUS 3RV1 Size S0, S1, S2, or S3 circuit breaker. The 110 V AC 50 Hz coil connects to the control circuit; when voltage falls below the dropout threshold the breaker trips, and the 2 NO leading auxiliary contacts change state before the main contacts open. No extra wiring to the breaker's load terminals is needed — the release draws its mechanical trip force from the breaker's stored-energy mechanism.","metaTitle":"Siemens 3RV1922-1CF0 SIRIUS undervoltage release, phased out","metaDescription":"Siemens SIRIUS 3RV1922-1CF0 undervoltage release, 110 V AC 50 Hz, 2 NO auxiliary switch, for Size S0-S3 breakers.

For a direct functional replacement in the 3RV1 platform, no drop-in alternative exists — the 3RV2 uses a different mounting interface. Stock of the 3RV1922-1CF0 is available through the surplus channel for existing 3RV1 panels."},{"question":"Will 3RV1922-1CF0 fit a panel built around 3RV1011-0GA10?","answer":"Yes, if the panel uses a 3RV1 Size S0-S3 circuit breaker. The 3RV1922-1CF0 mounts directly to any 3RV1 Size S0, S1, S2, or S3 breaker. The 3RV1011-0GA10 is a Size S00 breaker — the release is compatible with S00 as well (S00 falls within the S0-S3 range)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1922-1CF0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RV1922-1CF0 when reusing this data.
