Description
The MCF25-NAR combination arrester type 1+2 for lightning protection potential equalization according to VDE 0185-305 (IEC 62305) is suitable for use in the pre-counter range according to the VDEW guideline. The MCF25-NAR can be used in buildings with lightning protection or in-line feed in TN-C systems. It is mounted on 40 mm busbars in the connection compartment on the line side. The protection level of <=1.5 kV protects the terminals in the system. The lightning current dissipative capacity is 25 kA (10/350) total and 8.5 kA (10/350) per pole, sequence extinguishing up to 50 kA with a max. pre-fuse up to 160 A GL/GG. The FS version is also equipped with a potential-free changeover contact, which enables remote signaling.
