ABB AF400-30-11 Three-Pole Contactor

ManufacturerABBModelAF400-30-11Product TypeThree-Pole AF Contactor

01Product Identification

ABB AF400-30-11 is a three-pole AF block contactor for motor starting, isolation, bypass, and power-distribution switching. The base designation includes one normally open and one normally closed auxiliary contact, but it does not identify a unique electronic-coil voltage; the full extended type or order code must be checked before ordering.

Configuration Control

Match the complete model, ratings, ordered variant, installed system, connections, and protection requirements before ordering.

02Key Features

  • Electronic coil interface provides wide control-voltage ranges across the available suffix variants.
  • Integrated surge suppression removes the need for an additional coil surge suppressor in the documented AF design.
  • Three main poles with one normally open and one normally closed built-in auxiliary contact.
  • Suitable for motor starting, isolation, bypass, and distribution switching within the published ratings.
  • Main-circuit bars support the high-current connection arrangement.
  • A broad accessory range is available for front and side mounting in supported assemblies.

04System Integration

Integration Checklist

  • Select the exact extended type or order code because AF400-30-11 is available with several coil-voltage ranges.
  • Confirm control voltage, frequency, coil suffix, terminal arrangement, auxiliary contacts, interlocks, overload protection, and upstream protection.
  • Coordinate the contactor with the motor duty and the required IEC or UL utilization rating.
  • Check panel space and busbar geometry against the selected ordered variant before replacement.

Verified Identity

Model: AF400-30-11

Type: Three-Pole AF Contactor

Manufacturer: ABB

05Applications

  • Starting and stopping three-phase motors.
  • Switching power-distribution and isolation circuits.
  • Bypass contactor duty in approved industrial power-control assemblies.
  • High-current control panels requiring an AF-series electronic-coil contactor.

06Lifecycle

  • Do not order from the base model alone when the installed coil suffix is unknown.
  • Record the complete label, order code, coil voltage, wiring, auxiliary blocks, and mechanical interlocks before removal.
  • Preserve the required utilization category; AC-3 motor duty and AC-1 general-use duty have different ratings.
  • De-energize all main and control circuits and follow ABB installation instructions.
  • After replacement, verify coil pickup and dropout, phase connections, auxiliary-contact logic, and protection coordination.

FAQFrequently Asked Questions

What is ABB AF400-30-11?

It is a three-pole AF-series block contactor for motor and power-circuit switching.

How many built-in auxiliary contacts are included?

The base configuration includes one normally open and one normally closed auxiliary contact.

What is the AC-3 current rating at 400 V?

ABB lists 400 A at 380/400 V and 55 °C for the documented AF400 configuration.

What motor power is listed at 400 V?

ABB lists 200 kW for AC-3 motor duty at 400 V.

Why is the coil voltage not fixed on this page?

AF400-30-11 is a base designation shared by several electronic-coil voltage variants, each identified by an extended type and order code.

Is 1SFL577001R7011 the only AF400-30-11 order code?

No. It identifies the 100...250 V AC/DC coil variant; other official order codes cover other coil ranges.
