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.



LightningController 1-pole for use in TN- and TT-systems.
MCD 50-B: Coordinated lightning arrester Type 1 (Class B) to DIN EN 61643-11 for interface 0 to
2 (LPZ) according to lightning protection zone concept to IEC 61312-1 and/or DIN VDE 0185-305.
Protection capability 50 kA 10/350 μs per pole
Conforms to VDN Directive, 2nd Edition 2004
Protection level < 1.3 kV
Line follow current quenching capacity 25 kA Ipeak
Including plug caps for identifying the connections
Enclosed, non-extinguishing discharge gap
Can be used in normal commercial distributor housings
Application example: compact overvoltage protection concepts in a separate housing. Installation
of arresters of requirement Class B+C in a distributor without decoupling inductivity and/or line
lengths, e.g. direct on mobile radio system technology.
