PLUGGABLE SPDS FOR DIN RAIL MOUNTING
BXT ML4 BE 24
Dimension drawing BXT ML4 BE
LifeCheck detects thermal and electrical
overloads after which the SPD has to be
replaced. Indication is performed by
DEHNrecord LC without contacting.
Space-saving combined lightning current and surge arrester module with LifeCheck for
protection of 4 single lines with common reference potential as well as unbalanced interfaces.
LifeCheck SPD control
Optimum protection for 4 single lines
For use according to the lightning protection
zones concept at boundaries 0A – 2 and higher
