Description
Combination arrester, type 1+2, 3-pole, for use in TN-C networks.
Completely pre-terminated and ready for connection, consisting of:
3x MCD 50-B: Type 1+2 (Class B) coordinated lightning current arrester 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 150 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.
