Details
The N-PE surge arresters of type DEHNgap C S are an ideal supplement to the single-pole DEHNguard S surge protective devices. Being total current arresters between the neutral and protective conductor in TT systems, DEHNgap C S surge arresters help to ensure fulfilling the requirements for protecting personnel and equipment in 3+1 and 1+1 configurations.
With their modern Red/Line design, DEHNgap C S surge arresters have exactly the same easy-to-use safety features as the DEHNguard S devices. The unique module locking system combines the spark-gap-based protection module and the base part to a powerful unit. Neither vibration during transport nor the enormous forces of discharge can loosen this connection. Nevertheless, the protection modules can be easily replaced without tools by simply pressing the easy-to-use module release button of the protection module. The mechanical coding of the protection module and base part ensures against installing an incorrect module.
Safety of DEHNgap C S surge arresters is increased by monitoring the arrester temperature and an integrated disconnector connected in series with the surge arrester.
The green and red indicator flags show the operating state of DEHNgap C S surge arresters.
Apart from this standard visual indication, DEHNgap C S ... FM features a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept. The N-PE surge arresters of type DEHNgap C S incorporate multifunctional terminals for connecting conductors and busbars, allowing easy wiring with other DIN rail mounted devices. Thus, a variety of applications can be easily connected in series according to IEC 60364-5-53 for optimal protection.
