ASTAT XT Soft Starter

Previous Generation: ASTAT XT soft starter 

Features and Benefits

  • Current ratings: 8A-1400A: 8, 17, 31, 44, 58, 72, 85, 105, 145, 170, 210, 310, 390, 460, 580, 820, 950*, 1100*, 1400*??? ?*=Non-UL
  • Line Voltage:
    - 3ph, 230-500V 50/60Hz. (Type QT1x, 1400V PIV ratings)
    - 3ph, 460-600V 50/60Hz. (Type QT2x, 1600V PIV ratings)
    - 3ph, 690V 50/60Hz. (Type QT3x, 1800V PIV ratings)
  • Frequency Range: 45Hz-65Hz, auto-tracking frequency range
  • Control Voltage: 230VAC, +10, -15%, 50/60Hz or 110VAC, +10, -15%, 50/60Hz
  • Motor Protection: IEC Class 10 or 20 and NEMA Class 10, 20 and 30 overload
  • Built-in Bypass Terminals: Extra power terminals are standard to allow easy installation of an external bypass contactor
  • Pump Control: Avoids overpressure at the end of the acceleration phase and suppresses hammering at the stopping phase
  • Communication Networks: Modbus RTU is built in, factory-installed DeviceNet or Profibus DP are optionally available
  • LCD Display & Six-Button Keypad: Saves time by setting up the ASTAT XT using full parameter descriptions instead of codes
  • In-Line or Inside-Delta Operation: Choose either traditional Line or Inside Delta operation, which allows the ASTAT XT to easily replace Y/D starters and allows the unit?s rating to be reduced by as much as 1.5 times
  • Torque Control: Controlled torque ramps produce results close to linear speed without tachometer feedback
  • Generator Supply: Helps minimize the negative effects caused by the generator voltage fluctuations during starting


  • Pumps
  • Fans
  • Compressors
  • Conveyors
