It operates on a 400V AC, 50Hz control supply and provides two normally-open (NO) auxiliary contacts for status feedback to the PLC or safety circuit. The leading HS (high switching) variant means the auxiliary contacts are mechanically linked to the main contact position — a requirement for certain safety-related interlocking schemes where you need positive indication that the breaker has dropped out. No phase-out or last-time-buy notice exists. Mounts onto the left side of a circuit breaker in the S0, S1, S2, or S3 frame size. It snaps into the accessory slot without adding DIN-rail width. The description notes compatibility with Fa. Lovato breakers in the same frame sizes — a cross-reference worth knowing if you are maintaining a mixed-brand panel. The 400V AC 50Hz coil is single-frequency; do not apply it on a 60Hz system without verifying the thermal rating, as the impedance changes with frequency and the coil may overheat or fail to hold in.","metaTitle":"Siemens 3RV1922-1CV00-0FQ0 Undervoltage Release, 400V AC, 50","metaDescription":"Siemens 3RV1922-1CV00-0FQ0 undervoltage release, 400V AC 50Hz, 2 NO contacts, for S0-S3 breakers.
