Voltage Limiting Devices

  • Electrical isolation of insulated track sections and earthed parts of installations
  • Safe equipotential bonding in case of a short-circuit or earth fault at the overhead contact line due to high-current-resistant welding of the electrodes
  • Discharge of lightning overvoltages without short-circuit formation due to lightning-resistant SDS ... voltage limiting device
  • Short-circuit withstand capability up to 25 kArms / 100 ms; 36 kArms / 75 ms
