Overview

The ABB AF38Z-30-22-20 is a DC-operated, 3-pole block-type contactor designed for controlling power circuits up to 690 V AC and 220 V DC. This model is specifically suited for managing 3-phase motors, rated for 25 HP at 480 V, and non-inductive or slightly inductive loads. It offers a general use rating of 50 A at 600 V AC and a rated operational power of 18.5 kW at 400 V AC-3. The AF38Z-30-22-20 features an electronic coil interface that accepts a wide control voltage range, specifically 12...20 V DC for this variant, simplifying global inventory and application across different voltage standards without coil changes. This design ensures compatibility with PLC outputs as low as ≥ 24 V DC at 500 mA, while also providing reduced holding coil consumption for improved energy efficiency. Built-in surge protection is integrated, eliminating the need for external surge suppressors and meeting SEMI F47-0706 compliance for short voltage dips and sags within its specified control voltage range. The contactor comes with a non-removable front-mounted auxiliary contact block providing 2 Normally Open (N.O.) and 2 Normally Closed (N.C.) contacts. Additional side-mounted add-on auxiliary contact blocks can be fitted for expanded functionality. Mechanically-linked auxiliary contacts are compliant with Annex L of IEC 60947-5-1, and N.C. mirror contacts adhere to Annex F of IEC 60947-4-1, ensuring operational safety and compliance. The AF38Z-30-22-20 has a weight of 0.400 kg and is manufactured by ABB - Electrification. For this specific DC-operated variant, polarity must be respected on the coil terminals (A1+ and A2-).
  • Controls power circuits up to 690 V AC and 220 V DC.
  • Suitable for 3-phase motors (25 HP @ 480 V) and non-inductive loads.
  • Rated 50 A general use @ 600 V AC and 18.5 kW @ 400 V AC-3.
