ABB AF40-30-11-14 — 42 A, 3-Pole Contactor with Wide-Coil Range
The ABB AF40-30-11-14 is a 3-pole contactor rated 42 A, with a coil that accepts 250–500 V AC/DC. The integrated 1 NO + 1 NC auxiliary contact block saves panel space over a separate add-on. The wide coil range simplifies BOMs where line voltage varies across sites.
The 42 A rating is the thermal current (Ith) for enclosed mounting — it governs the continuous load the contactor can carry in a standard panel without forced cooling. The 250–500 V AC/DC coil means one part covers both 277 V and 480 V control circuits, and the DC tolerance simplifies battery-backed or rectified-supply installations. The 1 NO + 1 NC auxiliary pair is factory-fitted, so no separate aux block order is needed for basic feedback or interlocking.
