9 A motor rating, 120 V AC coil — what it means for the panel
The A9-30-10-84 is an ABB IEC contactor on the A9 frame, rated 9 A for motor switching (21 A general-purpose resistive load) at 600 V. That 9 A figure is the AC-3 motor current — the value that determines whether this contactor can start and stop a motor under load without welding the contacts. For a 3-pole contactor, this covers most small three-phase motors up to about 4 kW at 400 V. The coil is 120 V AC — a standard control voltage in North American panels. The built-in 1 N.O. auxiliary contact saves a separate add-on block for basic feedback to the PLC or status lamp.
End-of-life — sourcing reality for the A9-30-10-84
No official successor order code is recorded from ABB for this exact A9 frame variant. If you need a current-production replacement, the closest functional match would be an ABB A-line or AF-series contactor with the same 9 A AC-3 rating and 120 V AC coil — but the mounting footprint and auxiliary contact arrangement may differ. Confirm the panel layout and wiring before substituting.
Where it fits — panel and load context
The A9-30-10-84 snaps onto a DIN rail in a control panel. It switches motor loads — pumps, conveyors, fans — up to 9 A in AC-3 duty, or resistive loads like heaters up to 21 A. The 3-pole configuration handles three-phase circuits; the 120 V AC coil ties into a standard control transformer or PLC output.
