ABB 1SDA014031R1 S6 Electric Operator, 120VAC/125VDC Coil

The 120VAC/125VDC coil is the headline spec. If your control transformer puts out 120VAC, this operator pulls in directly. If you're running a 125VDC battery-backed control bus — common in substations and industrial switchgear — the same operator works without a separate DC-rated relay or voltage converter. That dual rating is the reason to pick this over a single-voltage operator; it reduces line-item count on the BOM and eliminates a potential miswire point during commissioning. At 1.90 kg, the operator adds noticeable weight to the breaker assembly. Factor that into DIN-rail or panel-mount calculations if the breaker is already near the rail's load limit. The weight also matters for shipping — a single operator ships as a small parcel, but a pallet of them adds up.
