Type 2 surge arrester - DGE
The DGE is a Type 2 AC Surge Protection Device (SPD) dedicated to protect sensitive equipment againstover voltage which may occur in the AC network during a storm (lightning) or during switching electric
power sources (industrial interferences)..
In association with DGT or DGX surge arresters (see diagram), the DGE surge arrester provides
common and differential surge protection for AC networks, following the CT2 configuration in
IEC 60 364-5-534 standard.
Protection is based on specific gas tube which provides much lower residual voltages and high
discharge current capability on 8/20μs impulses.
The DGE is built with a plug-in module and a fixed base, which allows an easy and fast maintenance.
