The perfect supplement:
the MB 50-3+NPE base

The four-pole MB 50 base, which is suitable for TN and TT systems, now complements the series of intelligent OBO MultiBase bases. The integrated NPE high-performance spark gap can now safely dissipate lightning currents of up to 50 kA (10/350). The orange housing and the blue rating plate make the integrated NPE spark gap stand out from the crowd. Known OBO benefits, such as the rotation of the cartridges and the optionally integrated remote signalling, are a matter of course.

Together with the V50 cartridge, they allow correct lightning protection equipotential bonding in buildings of protection classes III and IV in accordance with VDE 0185-305.
