It operates at 500 V AC, 50 Hz and includes a leading auxiliary switch with 2 normally-open contacts. ## Integration note The release mounts directly onto the side of a 3RV1 circuit breaker in sizes S0, S1, S2, or S3. No additional DIN-rail space is consumed; it clips onto the breaker housing. The 2 NO auxiliary switch signals the undervoltage state back to the control system.","metaTitle":"Siemens 3RV1922-1CS0 SIRIUS Undervoltage Release, 500V AC","metaDescription":"Siemens SIRIUS 3RV1922-1CS0 undervoltage release, 500V AC 50Hz, 2 NO auxiliary switch, IP20 finger-safe front.
