The front is finger-safe to IP20 per IEC 60529, meaning accidental contact during panel access is prevented — standard for control-panel components mounted behind a door. This part carries a lifecycle stage of 'current' but the description explicitly marks it as a phased-out product. The official successor is the SIRIUS 3RV2 series — same form factor and function, but the exact order code for the replacement should be verified against the panel BOM. ## Integration Note Mounts directly onto the SIRIUS 3RV1 circuit breaker via the accessory slot — no additional wiring required beyond the release coil connections. The IP20 finger-safe front means it can be installed in a standard IP20 enclosure without needing a separate cover over the release. Panel builders should note the 100 V operating coil; verify control transformer taps before commissioning.","metaTitle":"Siemens 3RV1902-1AG6 SIRIUS Undervoltage Release, IP20","metaDescription":"Siemens SIRIUS 3RV1902-1AG6 undervoltage release, 100 V, IP20 finger-safe front.
