ABB AF40-30-00-11 40A 3-Pole Contactor 24V DC

The ABB AF40-30-00-11 is a 40A 3-pole contactor with a 24V DC coil, designed for motor starting and load switching in DC-controlled automation systems. Its 40A rating suits motors up to approximately 18.5kW at 400V, making it a practical choice for UAE industrial, process, and building automation panels with 24V DC control circuits.

Key Features

  • 40A AC-3 rating — suitable for motors up to ~18.5kW at 400V
  • 24V DC coil for PLC and 24V DC automation control systems
  • 3-pole main contacts (3NO)
  • DIN rail or screw mounting
  • Genuine ABB AF-range quality

FAQ

  • What does this contactor control?
    It's an electrically-operated switch used to make/break a load circuit repeatedly under remote or automatic control — commonly lighting banks, motors, HVAC equipment, or heating loads switched via a timer, BMS, or control relay.
  • Does this need a separate overload relay for motor protection?
    Yes, if it's controlling a motor — a contactor alone doesn't protect against sustained overload. Pair it with a compatible thermal overload relay (see ABB's matching TF/TA-series relays) to form a full motor starter.
  • Can I control this contactor with a timer or BMS?
    Yes — the coil is designed for remote switching from a timer, PLC, BMS, or control relay rather than direct manual operation, making it suited to automated load switching.
  • Can I install this myself?
    No. Contactors are wired into live control and power circuits and must be installed by a licensed electrician in accordance with UAE wiring regulations.
