Safety TUV Type 1 Surge Protection Device Connect Conductors And Busbar

50ka 1 single Phase Type 1 Surge protective device TUV BR-50GR 1+1

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-25GR NPE help to ensure fulfilling the requirements for protection of personnel and equipment in "1+1"  circuits. The Epcos discharge spark gaps were specifically used to meet this challenge. With a discharge capacity up to 50 kA (10/350 μs), they fulfill the most stringent requirements of national and international lightning protection standards. Their leakage-current-free spark gap design allows the devices to be used upstream of the meter panel .

     The BR-25GR 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-25GR surge arresters without additional decoupling coil. If lightning current arresters are to be installed along with surge arresters at the same location, no additional coil is required thanks to the low voltage protection level of BR-25GR NPE.
     The design and installation of BR-25GR NPE arresters are adapted to the unique nature of low-voltage switchgear installations and entirely complement the use of BR-25GR arresters.
The multifunctional terminals of the DIN rail mounted BR-25GR NPE devices are suitable for connecting conductors and busbars, allowing comfortable wiring with other DIN rail mounted terminals.
