The AF116-40-11-11: Four-pole contactors like this one are typically deployed for three-phase motor circuits plus a neutral pole, or for resistive loads where a fourth pole handles a separate control circuit. The AF116 frame size slots into ABB's modular contactor range, sharing accessories like auxiliary contact blocks and mechanical interlocks across the family.
Integration Notes
The AF116-40-11-11 mounts on a DIN rail, which means it clips into the standard 35 mm rail found in most industrial enclosures. When wiring, note that the coil terminals and main pole terminals are clearly segregated on the contactor face — a detail that speeds up panel wiring and reduces the chance of mis-routing control vs. power conductors.
