The release snaps onto 35 mm DIN rail and fits SIRIUS 3RV breaker frames S00, S0, S2, and S3. Two normally-open leading auxiliary contacts provide status feedback ahead of the main contacts — useful for signaling a pending dropout to a PLC or safety relay before the load actually drops. The release measures 18.5 mm wide by 90 mm high by 68 mm deep. That 18.5 mm width matches a single 18 mm DIN module pitch, so it occupies one position on the rail. Snap-on mounting means no tools for installation — press onto the DIN rail alongside the breaker. ## Environmental and electrical ratings Insulation voltage is rated 690 V AC with pollution degree 3. The control supply voltage is AC only.","metaTitle":"Siemens 3RV1922-1CV1 SIRIUS undervoltage release, 415 VAC/50","metaDescription":"Siemens SIRIUS 3RV1922-1CV1 undervoltage release for motor circuit breakers S00-S3.
