ABB AF12Z-30-10-21 Three Phase AC Magnetic Contactor

ABB AF12Z-30-10-21 is a three-pole AC magnetic contactor designed for controlling three-phase power up to 690 V AC, with a continuous operating current Ie of 28 A at 40 °C ambient. Part of the AF12Z family, it uses an electronic coil interface that reduces pull-in and holding power and accepts control voltages of 24–60 V AC (50/60 Hz) or 20–60 V DC, enabling direct interfacing with common PLC outputs. The unit ships with 1 normally open auxiliary contact and no normally closed contact, all housed in a compact enclosure measuring 92.3 mm high x 45 mm wide x 77 mm deep. Designed for motor loads in industrial settings, it withstands voltage dips and voltage sag, making it suitable for machines, conveyors, and HVAC equipment where reliable 3‑pole switching is required. Short-time current ratings (Icw) vary by duty cycle, for example up to 150 A for 10 seconds and up to 300 A for 0.1 seconds at 40 °C in free air, reflecting robust startup capability while staying within its 690 V ratings. The AF12Z-30-10-21 combines a compact footprint with versatile coil options to simplify control circuits and reduce wiring complexity in industrial panels.
