Combination arrester, 4-pole, with visual function display, for use in TN-S and TT networks.

Completely pre-terminated and ready for connection, consisting of: MCD50BOS: Type 1 (Class B) coordinated lightning current arrester to DIN EN 61643-11. MCD125BNPE: Coordinated N-PE spark gap, type 1 (Class B) to EN 61643-11 for use inTN-S and TT systems. Interface 0 to 1 according to lightning protection zone concept accordingto IEC 61312-1 and DIN VDE 0185-305.

• Arresting capacity 50 kA (10/350 μs) per pole (L-N)

• Arresting capacity 125 kA (10/350 μs) per pole (N-PE)

• Power consumption < 26 mW/pole• Protection level < 1.3 kV

• Line follow current quenching 25 kA Ipeak

• Incl. plug caps for identifying the connections• Encapsulated, non-extinguishing spark gap

• Can be used in standard distributor housings.Application: Lightning protection equipotential bonding for buildings, even with external lightningprotection of classes I to IV in standard distribution housings.
