Description
Combination arrester, type 1+2, 4-pole, for use in TT and TN-S networks.
Completely pre-terminated and ready for connection, consisting of:
3x MCD 50-B: Coordinated lightning current arrester, type 1+2 to EN 61643-11 and
1x MCD 125-B/NPE: Coordinated N-PE spark gap, type 1+2 to EN 61643-11. For interface 0 to 2 (LPZ) in accordance with lightning protection zone concept to IEC 62305 and/or VDE 0185-305.
• Lightning protection equipotential bonding to VDE 0185-305 (IEC 62305)
• Lightning current arresting capacity to 50 kA (10/350) per pole and up to 125 kA (10/350) in total
• Protection level < 1.7 kV allows device protection
• Short-circuit resistance 10 kA, arrester backup fuse to 500 A gL/gG
• Encapsulated, non-extinguishing spark gaps
Application: Industrial systems and buildings with external lightning protection of the classes I to IV.
