Basic circuit diagram BXT ML4 BE 36
Dimension drawing BXT ML4 BE 36
Space-saving combined lightning current and surge arrester module with LifeCheck feature for protecting four single lines sharing a 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 / SCM / MCM reader.
