  The manufacturer's catalogue specifies 3 × 140 × 10 mm busbars for HiAN40 at the 4000 A rating. Temperature derating reduces the allowable current to approximately 3880 A at 50°C and 3560 A at 60°C under the catalogue's specified conditions.

  Dimensions – 3-Pole Draw-Out Version

  For the HiAN40 3-pole draw-out ACB, the catalogue gives approximately:

  • Width: 420 mm
  • Overall width with associated dimensions: approximately 480.4 mm
  • Height: approximately 462–481 mm depending on mounting/busbar arrangement
  • Depth: approximately 477.6 mm
  • Panel cut-out: approximately 292 mm
  • Mounting hole: Ø14 mm
  • Terminal mounting holes: Ø11 mm

  The exact dimensions depend on whether the breaker uses horizontal or vertical busbars.

  Protection & Accessories

  The HiAN40 can be equipped with Hyundai's APR electronic protection relays, including functions such as:

  • Long-time overcurrent protection
  • Short-time overcurrent protection
  • Instantaneous overcurrent protection
  • Ground-fault protection, depending on APR configuration
  • Shunt trip (SHT)
  • Undervoltage trip (UVT)
  • Motorized spring charging
  • Auxiliary contacts
  • Draw-out position indication
  • Remote ON/OFF operation
  • Anti-pumping function

  For a 3-pole HiAN40 used on a 3-phase, 4-wire system with ground-fault protection, Hyundai specifies a 4000/0.2 A neutral CT, Class 1.0.
