lightning protection zones concept at
the boundaries from 0 A – 2 and higher
Basic circuit diagram BXT ML4 BE
Dimension drawing BXT ML4 BE
Space-saving combined lightning current and surge arrester module with LifeCheck feature for protecting
four single lines with common reference potential as well as unbalanced interfaces. If
LifeCheck detects thermal or electrical overload, the arrester has to be replaced. This status is indicated
contactlessly by the DEHNrecord LC / MCM reader.
