Basic circuit diagram BXT ML2 MY E
Space-saving surge arrester module with LifeCheck feature for protecting two pairs of stranded signal
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.
Presumably available in the second quarter 2012
• LifeCheck SPD monitoring
• Distinctive “Y“ circuit
• For installation in conformity with the
lightning protection concept at the
boundaries from 0 B – 2.
