1650 A contactor for heavy motor and resistive loads
The ABB AF1650-30-11-70 is a 3-pole contactor rated for 1650 A at 600 VAC, with a 100-250 V AC/DC control coil. That 1650 A continuous rating places it in the heavy industrial class — sized for large motor starters, capacitor banks, or resistive heating loads where a smaller contactor would weld or overheat under sustained inrush. The 100-250 V AC/DC coil gives you flexibility on control voltage; same part works on a 120 V or 240 V control circuit without swapping coils.
At 1650 A, this contactor is a bolt-on frame, not a DIN-rail snap — expect bus-bar connections and a dedicated mounting footprint in the enclosure. The 100-250 V AC/DC coil means the control transformer or power supply can be shared across a mixed AC/DC control scheme, which simplifies panel wiring when you have both PLC outputs and relay logic on the same cabinet.
