What It Is and Where It Fits
The ABB AF305-40-00-13 is a 4-pole contactor with a 100-250 V coil, part of the AF305 series. It switches motor loads or resistive loads in a control panel — think conveyors, pumps, or lighting banks where a 4-pole break is needed. The coil range covers 100-250 V AC/DC, so it handles standard 110 V or 220 V control circuits without a separate transformer tap.
Integration Notes
Mounts on a DIN rail in the enclosure. The 4-pole configuration means it breaks all three phases plus neutral — common for motor disconnect or distribution panels requiring full isolation. Coil draw is sized for standard PLC or relay outputs; verify the control transformer can handle the inrush at 100 V if that's your minimum control voltage.
