The ABB AF09Z-22-00-20 is a 4-pole IEC contactor from the AF-Line series, AF09 frame, rated for 9 A at 600 V. It carries a 12 VDC coil and is configured with two normally-open and two normally-closed auxiliary contacts. This is a general-purpose contactor sized for switching loads like small motors, resistive heaters, or lighting banks in a control panel.
For a 4-pole contactor this means it can switch a 3-phase motor plus a neutral, or handle two independent single-phase loads. The 12 VDC coil is a low-voltage control signal — common in PLC-driven panels or battery-backed safety circuits. The 600 V rating covers 480 VAC systems with margin.
The 4-pole width is roughly 45 mm — plan for that footprint when laying out the enclosure. The 12 VDC coil draws minimal current from the control supply, but verify the PLC output or relay driving it can handle the inrush. Spring-cage terminals on the AF-Line accept 0.2–2.5 mm² wire; strip length 8 mm.
