It operates on a 220...250 V AC/DC control supply, meaning it can be driven from either an AC control transformer or a DC power supply without modification — useful when the control voltage in the panel is already 230 VAC or 220 VDC from a battery-backed bus. This mechanism mounts directly onto the front of a 3RV1.8 circuit breaker, converting a manual breaker into a remotely operated device. The spring-energy-store design means the mechanism charges a spring on energization and uses that stored energy to toggle the breaker — so the switching action is consistent regardless of control voltage sag. In a panel, this eliminates the need for a separate contactor and control relay for the breaker's remote trip/reset function, saving DIN-rail space and wiring. The 220...250 V AC/DC coil means it integrates cleanly into standard European control circuits (230 VAC) or DC systems common in UPS-backed panels. Verify the control supply matches the coil range before commissioning — the mechanism draws its rated inrush only during the spring-charge cycle, not continuously.","metaTitle":"Siemens 3RV1986-3AP3 SIRIUS Motorized Operating Mechanism, 2","metaDescription":"Siemens SIRIUS 3RV1986-3AP3 motorized operating mechanism with spring energy store. 220-250 V AC/DC.
