Description
Combination arrester set, type 1+2, 3-pole, with visual function display, for use in TN-C networks:
Completely pre-terminated and ready for connection, consisting of:
3 x MCD 50-B-OS: Type 1+2 coordinated lightning current arresters to DIN 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
• Power consumption < 26 mW/pole
• Encapsulated, non-extinguishing spark gaps
Application: Industrial systems and buildings with external lightning protection of Classes I to IV.
