The ABB AF38-40-00-13 is a 4-pole electrical contactor from the AF38 series, designed for AC or DC operation with a coil voltage covering 100-250 VAC at 50/60 Hz and 100-250 VDC. Its 4 normally open main contacts and screw terminals make it a straightforward fit for motor switching and resistive load control in industrial panels where a single coil voltage range needs to cover both AC and DC control circuits. Rated for motor loads up to 25 HP at 550-600 VAC, this contactor handles the inrush and breaking demands of induction motors in that power band. The maximum breaking capacity of 200 A at 690 V and 500 A at 440 V gives the integrator headroom for fault clearing in 400 V class systems, though the actual interrupting duty depends on the upstream protection coordination.
The wide-range coil (100-250 VAC/VDC) simplifies panel design — one part number covers both 120 V and 240 V control circuits without a separate coil change. The control circuit tightening torque of 11 in-lb and acceptance of 16-6 AWG wire on the main terminals (22 in-lb torque) match standard panel wiring practices. Operating temperature from -40 to +70 °C means it lives in unheated enclosures or near ovens without derating.
