It snaps onto the breaker's side — no separate DIN-rail slot needed — and connects via screw terminals. The coil is rated for 350-415 V AC at 50/60 Hz, and it can handle a short-duration 330-500 V AC or DC pulse for 5 s, plus a continuous 100% duty at 330-500 V AC. That means you can wire it to an emergency-stop circuit or a PLC output and drop the breaker from a distance without running heavy power cables into the panel. This release snaps directly onto the left side of any 3RV2 motor circuit breaker in frame sizes S00, S0, S2, or S3. It adds 18.5 mm of width to the assembly and extends 68 mm deep — that's about the same as the breaker body, so you don't lose extra cabinet depth. The screw terminals accept standard control wiring, and the snap-on fastening means no tools for installation or removal. If you're retrofitting an existing panel, measure the side clearance: the release sits flush against the breaker, but you need access to the terminal screws on the front face. Siemens lists the 3RV2902-1DV0 as active — no end-of-life notice or last-time-buy date. It remains a standard catalog item, not a phase-out or NRND part.","metaTitle":"Siemens 3RV2902-1DV0 Shunt Release, 350-415 V AC, SIRIUS","metaDescription":"Siemens SIRIUS 3RV2902-1DV0 shunt release for 3RV2 motor circuit breakers. 350-415 V AC, 50/60 Hz, screw terminals, snap-on DIN rail.
