It accepts a 20-24 V AC control supply at 50/60 Hz and is rated for continuous duty at that voltage, with a separate 5-second ON period rating of 20-70 V AC or DC for applications needing a higher momentary pull-in voltage. The shunt release snaps onto the breaker's side via the standard DIN-rail mounting system — no additional panel space required beyond the breaker's own 19 mm width. The 20-24 V AC control supply is the continuous-duty range — the coil can be energized indefinitely at that voltage. The 5-second ON period rating of 20-70 V AC or DC is a separate, higher-voltage capability for applications where the trip signal is a short pulse, not a sustained hold. This dual rating is unusual for a shunt release and gives flexibility in control schemes: use the continuous range for standard undervoltage release circuits, or the short-pulse range for PLC-driven trip commands that clear after the breaker opens. The 20 ms break time is the mechanical opening delay once the coil is energized — fast enough for most motor protection coordination schemes.","metaTitle":"Siemens 3RV2902-2DB0 SIRIUS Shunt Release, 20-24 V AC, 50/60","metaDescription":"Siemens 3RV2902-2DB0 SIRIUS shunt release for 3RV2 motor circuit breakers. 20-24 V AC 50/60 Hz control supply, 690 V rated insulation, spring-loaded terminals.
