Surge arrester schematic:
Class 1 Type 1 Surge Protection Device Application:
• Being total current arresters between the neutral and protective
conductor in TT systems, the single-pole N-PE lightning current
arresters of type BR-50GR NPE help to ensure fulfilling the
requirements for protection of personnel and equipment in "1+1"
circuits.
• The BR-50GR NPE coordinated NPE lightning current arresters hold
a special position among total current arresters. Due to their low
voltage protection level, they can be directly coordinated with
N-PE surge arresters of the BR-50GR surge arresters without
additional decoupling coil.
• BR-50GR NPE devices are suitable for connecting conductors and
busbars, allowing comfortable wiring with other DIN rail mounted
terminals.
• Widely used in mobile communication base stations, microwave
communication bureaus/stations, telecommunication rooms, industrial
mining, civil aviation, financial securities and other power
systems.
Surge arrester nedir?
Bir aşırı gerilim koruyucusu (Surge Arrester), geçici voltaj
dalgalanmalarının elektrikli ekipmanlara zarar vermesini önlemek
için kullanılan bir koruyucu cihazdır. Sistemdeki anormal voltaj
tepe noktalarını tespit edebilir ve aşırı enerjiyi hızla toprağa
yönlendirebilir, böylece voltaj dalgalanmalarının hassas
ekipmanlara zarar vermesini önleyebilir.
Surge arrester purpose: A surge arrester, as the name suggests, is
a device that protects other electrical equipment by “arresting” or
discharging surge currents.
