VSSC4 surge protection terminal with gas discharge tube

Surge protection with individual components

With gas discharge tubes in terminal design

Gas discharge tubes/spark gaps (GDT) are used in the terminal design. They are approved for a maximum DC voltage, which is printed on the component. Any voltage greater than the specified value is safely discharged in approx. 10-100 µs. Gas discharge tubes are used for higher power ratings. Any voltage greater than that specified is safely discharged in approx. 10-100µs. Gas discharge tubes are used for higher power ratings.
