LIGHTNING CONTROLLER MC50-B/O

MC 50-B 0 VDE Protection Module Type 1 surge protectors conduct the discharge current of a direct lightning strike to ground via the grounding electrode and limit the resulting overvoltages to a safe level. According to SPD standard EN 61643-11 Type 1 According to SPD standard IEC 61643-11 Class I Installation method base unit Model 1-pole Protection class IP 20 Discharge capacity (8/20) [total] (kA) 50 Ignition time (ns) <100 Follow current interruption capacity lpeak (kA) 25 Follow current interruption capacity leff (kA) 12.5 Maximum continuous voltage (V) 255 Lightning current (10/350) (kA) 50 Short-circuit withstand (kA) 25 Nominal discharge current (8/20) (kA) 50 Nominal voltage (V) 230 Maximum fuse rating (A) 500 Protection level (kV) <2.0 No marking on device Distribution unit TE (17.5 mm) 2 Temperature range (°C) -40 : +85 When a direct lightning strike hits a building protected by an external lightning protection system, large potential differences can arise between the building and installed systems (electrical, telecommunications cables), leading to dangerous fires and damage. Nearby lightning strikes generate strong magnetic fields that can damage electrical equipment. But even lightning strikes up to 2 km away can generate dangerous overvoltages in the building's electrical equipment. OBO provides all necessary products for reliable lightning protection: surge protectors, overvoltage protectors, potential equalization and grounding accessories.
