ABB AX Contactors

Motor and power-circuit switching

ABB’s AX catalogue describes AC-operated three-pole contactors for motor and power-circuit switching. Main contacts switch the load; auxiliary contacts provide control or indication functions. The photographed AX09 is a product example, not a statement of ratings for every model in the list.

Select the duty and complete version

• Identify the load and utilization category: AC-3 motor duty and AC-1 non-inductive or slightly inductive duty have different rating conditions. Match the published rating to the actual load and operating voltage.
• Confirm main-circuit voltage, motor power or load current, switching duty and ambient conditions using the specific contactor documentation.
• Specify the coil control voltage and frequency separately from the main-circuit voltage. A suffix or model name alone is insufficient to establish all ratings.
• Confirm required auxiliary contacts, overload protection, short-circuit protection and the tested coordination of the complete starter assembly.
• Check installation dimensions, terminals, mounting and the exact accessory reference. Do not assume universal accessory or replacement compatibility.

Catalogue and historical-model boundary

The model list retains existing AX references, including historical versions. The ABB Asia catalogue describes particular product groups and voltage versions; its ratings and IEC or regional approvals must not be generalized to every listed code. Unconfirmed historical parameters, certifications and replacement relationships require the complete model, nameplate and applicable ABB documentation.

Information for quotation

Send the full product model, ABB Order Code, quantity and destination country. For selection, include load or motor details, main-circuit voltage, coil voltage/frequency, required auxiliary contacts and protection arrangement. For an existing installation, add a nameplate photo and dimensions or assembly details.
