ABB AFS30-30-22-11 Industrial Grade AC Contactor

ABB AFS30-30-22-11 is a three‑pole safety contactor in ABB’s AFS family, designed for industrial machine safety circuits and safety‑PLC interfaces. It features 2 normally open and 2 normally closed auxiliary contacts, a main circuit rated for 32 A in AC‑3 duty at 415 V (60 °C ambient), and it also provides AC‑1 ratings up to 50 A at 690 V (40 °C ambient) with ratings declining at higher temperatures (42 A at 60 °C, 37 A at 70 °C). The coil accepts 24–60 V AC at 50/60 Hz or 20–60 V DC. The enclosure measures 86 mm high, 45 mm wide, and 119.5 mm deep, and tightening torques are 1.2 N·m for auxiliary and control circuits and 2.5 N·m for the main circuit terminals. Short‑circuit withstand (Icw) is specified for multiple time durations, including 350 A for 10 s, 50 A for 15 min, 150 A for 1 min, 700 A for 1 s, and 225 A for 30 s, with additional values such as 140 A for 0.1 s and 100 A for 1 s at 40 °C ambient in free air from a cold state. This model, designated AFS30‑30‑22‑11, is intended for reliable, safety‑critical switching of power loads in industrial installations and integrates with safety‑related control wiring and auxiliary feedback required by safety circuits.
