The Eaton A110-30-11-84 is a 3-pole IEC contactor from the A-Line series, A110 frame size, rated for 110 A motor current and 140 A general-purpose load. The coil pulls in on 120 V AC. It ships with one N.O. and one N.C. auxiliary contact block integrated — no separate add-on needed for basic feedback or interlocking.
What the 110 A rating means for fit
The 110 A figure is the motor current rating under AC-3 duty — the load side for switching three-phase induction motors. The 140 A general-purpose figure covers AC-1 resistive loads. For a panel builder, the 3-pole block with 120 V AC coil is a standard combination that drops into an existing A110 frame footprint; the built-in aux contacts save one DIN-rail slot versus a separate contact block.
