EPG/100/250 & 250S - High Power GDT for Equipotential Bonding SPD
The EPG/100/250 and the EPG/100/250S are high power isolating Gas Discharge Tubes (GDT), intended for equipotential bonding of structures or components that cannot be directly bonded to earth during normal operation (for example pipelines with cathodic protection systems).
In the event of a potential difference developing between the parts connected with this device, the GDT breaks over and connects the parts for the duration of the overvoltage (Typical resistance at initial breakover is 0.001 to 0.002Ω).
After the overvoltage has been cleared, the device returns to its high resistance state.
These devices are IP66 rated, allowing for installation both indoors and outdoors, as well as in damp or subterranean areas. For lightning protection equipotential bonding in accordance with EN 62305-3 and EN 62561-3.
