It accepts a control supply of 20-24 V AC at 50/60 Hz, with a 100% duty cycle at 24 V and a 5-second ON period for the extended 20-70 V AC or DC range. This is a phased-out product; the official successor is the SIRIUS 3RV2902-1DB0. The IP20 finger-safe front (IEC 60529) protects against accidental contact with live parts from the front — standard for enclosed panel installations. For a BOM line that still specifies the 3RV1902-1DB0, the 3RV2902-1DB0 is the direct drop-in replacement from the same SIRIUS family, sharing the same function and footprint. No rewiring or panel modification should be needed when substituting the successor. At 18.5 mm wide and 68 mm deep, this shunt release fits circuit breaker frames S00, S0, S2, and S3. Rated insulation voltage 690 V with pollution degree 3. The AC control coil draws power only during the trip pulse.","metaTitle":"Siemens 3RV1902-1DB0 SIRIUS Shunt Release, 20-24 V AC, 50/60","metaDescription":"Siemens SIRIUS shunt release 3RV1902-1DB0, 20-24 V AC 50/60 Hz, for circuit breaker sizes S00-S3.
