Product description
Combination arrester, type 1+2, 1-pole, for use in TN and TT networks:
MCD 50-B-OS: Coordinated lightning current arrester, type 1+2 to EN 61643-11 with visual function display. For interface 0 to 2 (LPZ) in accordance with lightning protection zone concept to IEC 62305 and/or DIN VDE 0185-305.
• Arresting capacity 50 kA (10/350 µs) per pole
• Power consumption < 26 mW/pole
• Protection level < 1.7 kV, allows device protection
• Line follow current quenching 10 kA
• lncl. plug caps for labelling the connections
• Encapsulated, non-extinguishing spark gap
• Can be used in standard distributor housings
Application: Compact surge protection concepts and installations in a distributor.
