DEHNguard modular with Advanced Circuit Interruption (Safe Dimensioning)
- New "Advanced Circuit Interruption" (ACI) technology integrated in the protection module, consisting of a switch / spark gap combination
- Due to ACI technology, no external backup fuse required
- Small cross-sectional area of 6 mm2 (Cu) fully sufficient *)
- TOV withstand capability provided even at 440 V (AC)
- High system availability due to selectivity with 35 A gG system fuses
- Completely leakage-current-free due to galvanic isolation by ACI switch unit
- Energy-coordinated within the Red/Line product series
- Vibration- and shock-tested as per EN 60068-2
- Push-in connection terminal
*) All active conductors should be wired so that they are short-circuit and earth-fault-proof
