What this part is and what it does
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. It switches motor and resistive loads in control panels and industrial machinery, using the 120 VAC coil to close three main power poles.
Key ratings and what they mean for fit
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. Pricing and availability are confirmed at quote time against an RFQ. Volume inquiries are welcome — same part, different passport, as the cross-border traders say. Genuine ABB product, no aftermarket copies.
