The AF300‑30‑11‑70 is a 3‑pole non‑reversing contactor from ABB’s AF series, designed for motor control, power‑circuit switching, and industrial applications.It supports a control‑voltage range of 100–250 V AC or DC (50/60 Hz), compatible with different control‑voltage supplies.The contactor includes 3 main contacts (normally open — 3NO) and built‑in auxiliary contacts (1 NO + 1 NC) for additional control or signaling circuits.Its robust design with integrated arc suppression and wide current/voltage capacity makes it suitable for heavy‑duty loads, such as three‑phase motors or non‑inductive/slightly inductive loads up to 690 V.
