The ABB A9M-30-10-84 is a 3-pole contactor from the A9 series, rated for 9 A with a 120 VAC control coil.
The 9 A rating covers resistive and moderate inductive loads at the rated voltage. Three poles switch all phases in a three-phase circuit. The 120 VAC coil is standard for North American control circuits running on 120 V line-to-neutral; verify coil pickup and dropout thresholds against your control transformer regulation.
Sourcing posture
The A9M-30-10-84 is available through independent distribution channels. Volume inquiries are welcome — same part, different passport, as the cross-border traders say. Genuine ABB product, no aftermarket copies.
