It operates on a 230/220V AC, 50Hz control supply and provides two normally-open (NO) auxiliary contacts with leading high-speed (HS) switching — meaning the HS contacts open before the main breaker trips, giving a fast status signal to a PLC or safety relay before the load circuit actually drops. ## Integration Notes This undervoltage release mounts directly into the S0–S3 SIRIUS circuit-breaker frame — no additional DIN-rail space is consumed beyond the breaker itself. The 2 NO HS contacts are wired to the control circuit; the leading HS function ensures the auxiliary contacts signal the undervoltage condition ahead of the main contacts opening, which is useful for sequenced shutdown logic or for triggering a holding brake before the motor loses power.","metaTitle":"Siemens 3RV1922-1CP00-0FQ0 Undervoltage Release, 230/220V AC","metaDescription":"Undervoltage release 230/220V AC, 50Hz with leading HS, 2 NO, for circuit-breaker size S0...S3.
