Coordinated Lightning Controller type MCD 50-B & MCD 125-B/NPE
The Type MCD 50-B Coordinated LightningController is a coordinated
lightning arrester, Type 1 (Class B) to DIN EN 61643-11, designed
to deflect high pulsed currents (10/350). It is used in lightning
protection zones (LPZ) 0 to 1 at building entrances, where it
provides for lightning protection potential equalisation with the
energy supply lines.
Due to the low-level protection (<1.3 kV), there are no
additional decoupling elements between the Coordinated Lightning
Controller and the downstream surge arresters.
The Type MCD 125-B/NPE total discharge gap is used in TN-S and TT
network systems between N and PE. It prevents voltage drag on the
conductor, thereby preventing impermissible, high contact voltages
at potential equalisation.
The Coordinated LightningController is preferred for use in compact
surge arrester concepts in a housing, as well as combined lightning
and overvoltage protector installations in a distribution.
