M · AC CONTACTORS

Choose the contactor by motor duty, voltage and coordination—not amperes alone.

The 2026 source manuals separate the NC1, NC2 and NC8 families by current range, construction and application. Use the exact family data before cross-referencing.

Cross-reference checks

Do not treat a current rating as a complete replacement match.

  • Utilization category and motor current at the actual line voltage
  • Coil voltage, AC/DC type and frequency
  • Main poles and auxiliary-contact arrangement
  • Mounting, terminal capacity and enclosure clearance
  • Overload-relay, interlock and accessory compatibility
