KC6-22Z

The ABB KC6‑22Z is a compact 3‑pole miniature contactor relay designed for switching control circuits and small to medium loads. It is suitable for AC or DC control circuits, offering reliable operation in control panels, automation equipment, building automation, HVAC systems, lighting, and other light-duty industrial or commercial applications. The KC6‑22Z features a low-power coil, which allows control via PLC outputs or other low-current control circuits. Its compact design supports DIN-rail or panel mounting, making it ideal for space-constrained installations.
