It operates on 220 V AC at 50 Hz and snaps onto a DIN rail, making it a straightforward add-on for existing SIRIUS breaker installations in control panels. This part is flagged as a phased-out product. The official successor is the SIRIUS 3RV2 series. For a BOM freeze or a line-down replacement, the 3RV1902-1AN0 is sourced to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. Snap-on mounting onto a 35 mm DIN rail per DIN EN 60715 is standard. The 18.5 mm width and 68 mm depth keep it compact on the rail, and the IP20 finger-safe front (per IEC 60529) means it's safe for vertical contact from the front in an enclosed panel. Rated insulation voltage is 690 V with pollution degree 3.","metaTitle":"Siemens 3RV1902-1AN0 SIRIUS Undervoltage Release, 220 V AC 5","metaDescription":"Siemens SIRIUS 3RV1902-1AN0 undervoltage release for motor circuit breakers S00-S3. 220 V AC 50 Hz, snap-on mount.
