Install as a three‑pole block contactor with a main circuit using 52 mm² copper/aluminum bars or up to 300 mm² rigid cables. Use 0.75–2.5 mm² flexible or 1–4 mm² solid auxiliary conductors for the control circuit. Torque main circuit and cable lugs to 45 N·m, mount in a space with IP20 coil terminals and IP00 main terminals, and consider add‑on auxiliary contact blocks for signaling.
The AF750N7‑30‑11‑71 complies with IEC 60947‑1 and 60947‑4‑1, EN 60947‑1/4‑1, and UL 508, with CSA C22.2 N°14 recognition and CE conformity. These certifications support safe integration into global motor protection and control schemes, reduce regulatory risk, and ease cross‑regional procurement and compliance documentation.
The contactor supports a control circuit voltage of 250–500 V for 50 Hz, 60 Hz, and DC operation, with coil consumption of 12 VA holding and up to 985 VA pull‑in per coil rating. Operating times range from 45–115 ms for energization to release, and the device handles up to 300 cycles per hour in AC‑1 and 300 cycles per hour in AC‑3, depending on duty.
Yes, it is designed for AC‑3 motor loads. At 415 V, it delivers up to 750 A, enabling up to 600 HP in typical 460–575 V systems, with suitable variations across voltage tiers. The device offers a robust 8 x Ie rated breaking capacity for AC‑3, supporting reliable motor starting and protection in heavy‑duty applications.
The AF750N7‑30‑11‑71 features a mechanical durability of about 3 million cycles, reducing replacement intervals and maintenance costs. Built‑in surge protection lowers external protection needs, and the wide control voltage tolerance minimizes nuisance trips due to supply variation, delivering lower total cost of ownership in demanding industrial environments.
