VSSC with gas discharge tubes (GDT)

Surge protection with individual components

With gas-discharge tubes in terminal design

Gas-discharge tubes / sparkover gaps (GDT) are designed with a terminal shape. They are approved for a maximum DC voltage, which is printed on the component. Any voltage greater than the amount specified is safely discharged within about 10-100µs. Gas arresters can be used for high-power applications.
