The Siemens SIRIUS 3RV5902-1DV0 is a shunt release designed for remote tripping of motor circuit breakers in the S00, S0, S2, and S3 frame sizes. It accepts both AC and DC control voltages across a wide band — AC 330-500 V at 50/60 Hz (5 sec ED) or AC 350-415 V at 50/60 Hz (100% ED), and DC 330-500 V (5 sec ED) — making it flexible for global panel builds where control supply varies. Snap-on mounting onto 35 mm DIN rail per DIN EN 60715 and an IP20 finger-safe front (touch protection per IEC 60529) mean it integrates directly into the same rail as the breaker, with no additional enclosure protection needed for the front face in a standard IP20 panel.
Voltage ranges and duty cycle
Two operating regimes are defined: a short-duty 5-second energisation (AC 330-500 V or DC 330-500 V) for momentary trip commands, and a continuous-duty 100% ED (AC 350-415 V) for applications that need the release held energised indefinitely.
Panel integration
At 18.5 mm wide and 68 mm deep, this release occupies a single 18 mm DIN slot alongside the breaker — no extra width for a separate enclosure. The screw connection matches the breaker terminal style, keeping wiring consistent across the row.
