The AF50-30-11-70 is a 3-pole IEC contactor rated 50 A continuous and 600 VAC, with a universal coil accepting 100-250 VAC or VDC. That 50 A figure is the AC-1 resistive rating — for motor duty (AC-3) you derate; typical AC-3 current for this frame is around 30-35 A, so size it for the load, not the line number. The wide coil range (100-250 V) covers common control voltages across 120 V, 208 V, 240 V circuits without needing a separate coil variant — one part number for multiple panel builds. Built-in 1 N.O. + 1 N.C. auxiliary contact block saves a DIN slot versus adding a separate block later. The AF-Line series uses an electronic coil interface that holds in with no hum and drops out cleanly below the dropout threshold — no AC coil buzz, no DC coil suppression diode to worry about.
Deployment context
Snaps onto DIN rail in a standard control panel enclosure. The 50 A rating suits motor starters, pump panels, conveyor controls, and lighting contactor banks where the load is resistive or lightly inductive. The universal coil simplifies stocking — same part for 120 V and 240 V control schemes.
