It accepts a control supply of 220-250 V AC/DC, making it a direct bolt-on accessory for those breaker frames — no separate panel wiring for the mechanism, just the control voltage. This mechanism clips directly onto the front of a 3RV1.6 or 3RV1.7 circuit breaker — no DIN rail or separate enclosure required. The spring-energy-store design means the mechanism charges a spring on power-up, then uses that stored energy to toggle the breaker contacts, so the switching action is independent of momentary supply dips. The 220-250 V AC/DC coil range covers common control voltages across both AC and DC systems without needing a separate rectifier or power supply change. Because the mechanism mounts directly on the breaker, it does not consume additional DIN-rail space — the assembly fits within the breaker's own footprint. For a panel-builder, that means no extra gland-plate planning or fill-factor recalculation: the existing breaker position handles the mechanism. Control wiring runs to the mechanism's screw terminals; wire sizing follows the coil's inrush and hold current per the breaker's datasheet.","metaTitle":"Siemens SIRIUS 3RV1976-3AP3 Motorized Operating Mechanism, 2","metaDescription":"Siemens SIRIUS 3RV1976-3AP3 motorized operating mechanism with spring energy store for size 3RV1.6, 7.
