It operates on 350-415 V AC at 50/60 Hz and snap-mounts onto a DIN rail, fitting breaker frames S00, S0, S2, and S3. This is the part you add when you need an undervoltage or remote-trip function on the line side of a motor protection breaker — common in conveyor, pump, and fan panels where a safety PLC or E-stop circuit needs to kill power without a manual reset. This shunt release carries a current lifecycle stage, but the manufacturer has flagged it as a phased-out product. The official successor is the SIRIUS 3RV2902-1DV0. The 350-415 V AC control voltage covers standard 400 V three-phase panels without a step-down transformer — the coil pulls straight from the line side. The 50/60 Hz rating means it works on either supply frequency. At 18.5 mm wide and 68 mm deep, it tucks into the same DIN footprint as the breaker it serves, so it does not eat extra rail space in a crowded enclosure. The 100% ON period means the coil can be energized continuously without overheating, which matters if the release is held in for long intervals between trips. ## Panel integration The 18.5 mm width matches the S00 frame breaker profile, so it aligns cleanly in a multi-row layout.","metaTitle":"Siemens 3RV1902-1DV0 SIRIUS Shunt Release, 350-415V AC","metaDescription":"Siemens 3RV1902-1DV0 SIRIUS shunt release for motor circuit breakers. 350-415V AC, 50/60 Hz, snap-on DIN mount.

Both are shunt releases for the same breaker frames (S00 through S3), but the 3RV2 series uses the updated SIRIUS platform. Confirm the control voltage matches your panel before swapping."},{"question":"Where can I buy the 3RV1902-1DV0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. Submit an RFQ for a firm delivery estimate."},{"question":"Does the 3RV1902-1DV0 fit the same panel as a 3RV1011-0GA10 circuit breaker?","answer":"The 3RV1902-1DV0 is a shunt release accessory, not a breaker. It mounts on the same DIN rail and fits breaker frames S00 through S3, which includes the S00 frame of the 3RV1011-0GA10. It will drop into a panel specified for that breaker without rewiring the rail, but verify the control voltage (350-415 V AC) matches your trip circuit."},{"question":"What are the key dimensions of the 3RV1902-1DV0?","answer":"Width is 18.5 mm, depth is 68 mm, height is 90 mm.
