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 kA_rms/ 100 ms; 36 kA_rms/ 75 ms
