Combination arrestor set, 4-pole, with visual function display, for use
in TN-S and TT networks:
Completely pre-terminated and ready for connection, consisting of:
MCD 50-B-OS: Coordinated lightning current arrestor, Type 1 (Class
B) to EN 61643-11. For interface 0 to 2 (LPZ) according to lightning
protection zone concept to IEC 61312-1 and DIN VDE 0185-305.
MCD 125-B/NPE: Coordinated N-PE spark gap, Type 1 (Class B) to
EN 61643-11 for use in TN-S and TT systems. For interface 0 to 1 in
accordance with lighting protection zone concept to IEC 61312-1
and/or DIN VDE 0185-305.
• Arresting capacity 50 kA 10/350 µs per pole
• Power consumption • Protection level • Line follow current
quenching 25 kA Ipeak
• lncl. plug caps for identifying the connections
• Encapsulated, non-extinguishing spark gap
• Can be used in standard distributor housings.
Application example: Compact surge protection concepts and
installations of requirement class B+C arrestors in a distributor
without decoupling inductances and/or line lengths, e.g. direct on
mobile radio system
