Coil range is 24...30 V AC/DC, so it works on either supply without a rectifier module. The front face carries IP20 touch protection per IEC 60529 — finger-safe for vertical contact, meaning an operator reaching toward the breaker terminals won't contact live parts through the release housing. That matters for panels that need a safe open-front design without a full cover. ## Integration note Wiring is straightforward: two terminals for the 24...30 V AC/DC supply. No auxiliary contacts are included in this release — the dropout signal is mechanical, not electrically reported back to a PLC unless a separate auxiliary switch block is added to the breaker.","metaTitle":"Siemens 3RV1952-1AA0 SIRIUS undervoltage release, 24-30 V AC","metaDescription":"Siemens 3RV1952-1AA0 SIRIUS undervoltage release, 24-30 V AC/DC, IP20 finger-safe front, for 3RV13 5.
