The ABB AF12Z-30-01-30 is a 3-pole contactor from the AF12Z series, fitted with a 24 VDC coil and one normally open plus one normally closed auxiliary contact (0NO1NC). The 24 VDC coil holds in at nominal voltage; dropout voltage is typically below 18 VDC — a common threshold for DC control circuits in panel builds. The three main poles switch motor or resistive loads up to the contactor's rated operational current; the auxiliary contact set provides feedback or interlock without an add-on block.
Deployment context
The 24 VDC coil suits PLC-driven or relay-logic control circuits common in machine-tool, conveyor, and pump panels. The 0NO1NC auxiliary contact provides a single feedback path — enough for a run-status signal or a holding interlock without an extra auxiliary block.
