Dimension drawing BXT ML2 BE
Basic circuit diagram BXT ML2 BE
Space-saving combined lightning current and surge arrester module with LifeCheck feature for protecting
two single lines with common reference potential as well as unbalanced interfaces, with
direct or indirect shield earthing. If LifeCheck detects thermal or electrical overload, the arrester has
to be replaced. This status is indicated contactlessly by the DEHNrecord LC / MCM reader.
• LifeCheck SPD monitoring function
• Optimal protection of two single lines
and line shield
• For use in conformity with the lightning
protection zones concept at the boundaries
from 0 A – 2 and higher
