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 to1 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 LightningController 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.
