Product description
Combination arrester, type 1+2, 4-pole, with visual function display, for use in TN-S and TT networks.
Completely pre-terminated and ready for connection, consisting of:
3x MCD 50-B-OS: Type 1+2 (Class B) coordinated lightning current arrester EN 61643-11.
1x MCD 125-B/NPE: Coordinated N-PE spark gap, type 1+2 EN 61643-11 for use in TN-S and TT systems.
Interface 0 to 2 (LPZ) according to lightning protection zone concept according to IEC 62305 and 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
• Power consumption < 26 mW/pole
• Encapsulated, non-extinguishing spark gap
Application: Industrial systems and buildings with external lightning protection of Classes I to IV.
