It's the part that drops the breaker when line voltage falls below the dropout threshold — critical in mining or mill environments where an unexpected restart after a brownout could pull a conveyor back online with a full load and no operator in the loop. The 2NO contact block signals the control system that the release has tripped. It mounts directly into the breaker's accessory slot — no separate DIN-rail bracket needed. ## Deployment Context Built for the pit and the mill: the 3RV breaker family is rated for high-vibration environments and combustible dust atmospheres. This UVR clips into the breaker's side-mounted accessory bay, so it doesn't eat up DIN-rail space. The 2NO contacts are wired back to the PLC or safety relay to confirm the release state before allowing a restart sequence.","metaTitle":"Siemens 3RV1922-1CV10-0FH0 Undervoltage Release, 415V AC / 4","metaDescription":"Siemens 3RV1922-1CV10-0FH0 undervoltage release for S0..S3 breakers. 415V AC 50Hz / 480V AC 60Hz, IT leading HS, 2NO.
