DEHNguard modular with Advanced Circuit Interruption (Safe Dimensioning)

New technology "Advanced Circuit Interruption" (ACI) integrated in the protection module, consists of a switch / spark gap combination
Due to ACI technology no external backup fuse required
Small connection cross-sections (6 mm² Cu) absolutely sufficient ^*)
TOV withstand also at 440 V (AC)
High system reliability, no tripping of 32 A gG fuses
Zero leakage current due to galvanic isolation by ACI switch unit
Energy coordination with other arresters of the Red/Line product family
Vibration and shock-tested according to EN 60068-2
Push-in connection system

*) All live conductors should be wired so that they are inherently short-circuit and earth fault proof
