Combination / lightning current arrester set MCD... Type 1+2 according to EN 61643-11. MCD 50-B/3: (3-pole) for use in 230/400 V for TN-C systems. Energetically coordinated with type 2 arresters and directly with terminal devices. Innovative multi-carbon technology with pluggable, encapsulated spark gaps. Complies with VDN guideline 2nd edition 2004, discharge capacity 50kA 10/350s per pole, line follow current extinguishing 10 kA max. required backup fuse 500 A, LPZ 0-2. The low protection level (Up <1.7 kV) makes the installation of decoupling inductors superfluous and offers protection directly to the terminal device. The arrester set is supplied complete, ready for connection and pre-installed. An application example: industrial feeders and buildings with lightning protection systems. 5 year warranty
