Lightning arrester set for TT and TNS networks - Lightning arrest for power supply 125kA MCD 50-B... – OBO – 5096879 – 4012195077091: Lightning arrester set for TT and TNS networks MCD 50-B 3+1 lightning impulse current (10/350 µs) 125kA, nominal discharge current (8/20) 125kA, maximum continuous voltage AC 255V, nominal voltage AC 230V, protection level 1.3kV, follow current extinguishing capacity 25kA, Type of mounting DIN rail TH35, size 8 HP, signaling on the device without, test class type 1, combi/lightning arrester set MCD... type 1+2 according to EN 61643-11. MCD 50-B/3+1: (4-pin) for use in 230/400 V TT and TN-S systems. Energetically coordinated to type 2 arresters and directly to end devices. Innovative multi-carbon technology with pluggable, encapsulated spark gaps. Corresponds to the VDN guideline 2nd edition 2004, discharge capacity 50kA 10/350µs per pole, mains follow current extinguishing 10 kA max. required back-up fuse 500 A, LPZ 0-2. The low protection level (Up <1.7 kV) eliminates the need to install decoupling inductors and provides protection directly to the end device. The arrester set is supplied complete, ready for connection and pre-installed. An application example: industrial feeds and buildings with lightning protection systems. 5 year warranty
