The ABB AFS38-30-22-11 is a safety contactor from the AFS38 series, classified under Safety Sensor Switches. It provides three main poles and two normally-open plus two normally-closed auxiliary contacts (2NO2NC), with a dual-range coil accepting 24-60 VAC or 20-60 VDC.
The 3-pole main contact set handles three-phase motor or load circuits in a safety-related stop or isolation function. The 2NO2NC auxiliary contact configuration provides two mirror contacts for feedback and two normally-closed contacts for status indication. The wide coil range (24-60 VAC / 20-60 VDC) covers both standard 24 VDC control voltages and higher AC control voltages up to 60 VAC, reducing the need for separate coil variants across different panel designs. The AC and DC ranges overlap, so a single part number can serve a mixed-voltage installation.
Deployment context
As a safety contactor, the AFS38-30-22-11 is intended for use in safety circuits that require forced-guided contacts — typically in emergency-stop chains, guard-door monitoring, or two-hand control stations where a welded contact must not go undetected. The 2NO2NC auxiliary set provides the normally-closed feedback path the safety relay expects to see when the contactor drops out.
