11 A motor rating — the fit check for your BOM line
The A12-30-01-84 is an ABB IEC contactor rated 11 A in AC-3 motor duty. The 120 V AC coil means the control circuit must supply 120 V AC, typically from a control transformer or a PLC relay output rated for AC pilot duty. The built-in 1 N.C. auxiliary contact block covers basic feedback or interlock wiring without a separate add-on.
EOL hot — what it means for sourcing
The 11 A motor rating and 120 V AC coil are the fixed parameters that must match the application; no substitute is pin-compatible without a design review.
The A12 frame is a standard IEC contactor footprint — it snaps onto a DIN rail (EN 50022) and occupies a single modular width. The 3-pole power terminals accept up to 4 mm² cable; the coil terminals are on the front face for easy access during panel wiring. The 1 N.C. auxiliary contact is factory-fitted on the left side of the contactor. If the application needs additional auxiliary contacts or a mechanical interlock for reversing duty, those are separate add-ons from the A-Line accessory family.
