Details

As total current arresters between the neutral and protective conductor in TT systems, the single-pole N-PE lightning current arresters of type DEHNgap M, DEHNgap Maxi, DEHNgap Maxi S and DEHNgap H M have the task of fulfilling the requirements for protecting personnel and equipment in 1+1 or 3+1 configurations. The creepage discharge spark gaps implemented were specifically developed to meet this challenge. With a discharge capacity up to 100 kA (10/350 µs), they fulfil the highest national and international lightning protection standards. Their leakage-current-free spark gap design allows the devices to be used in areas upstream of the meter panel according to the German VDN guideline.
The DEHNgap M, DEHNgap Maxi S and DEHNgap Maxi coordinated N-PE lightning current arresters have a special status among total current arresters. Due to their low voltage protection level, they can be directly coordinated with N-PE surge arresters of the DEHNguard M family and DEHNgap C S surge arresters without an additional decoupling coil. If lightning current arresters are to be installed along with surge arresters at the same location, no additional DEHNgap C S is required thanks to the low voltage protection level of DEHNgap M and DEHNgap Maxi.
The design and installation of DEHNgap Maxi S arresters are adapted to the unique nature of low-voltage switchgear installations and entirely complement the use of DEHNbloc Maxi S arresters.
The multifunctional terminals of the DIN rail mounted DEHNgap M and DEHNgap H M devices are suitable for connecting conductors and busbars, allowing convenient wiring with other DIN rail mounted terminals. With its functional Red/Line design, DEHNgap M combines safety and ease of use in a single device. The mechanical operating state / fault indication as well as the unique module locking system stand for fulfilling high safety requirements. The module locking system fixes the protection modules to the base part. Neither vibration during transport nor the enormous forces of discharge can loosen the protection modules. Nevertheless, they can be easily replaced without tools by simply pressing the module release button of the protection module. Each protection module is mechanically coded to avoid installing an incorrect module. Apart from the standard visual indication of DEHNgap M, DEHNgap M ... FM features a three-pole remote signalling terminal. As the remote signalling contact is designed as a floating changeover contact, the remote signal can, depending on the circuit concept, be used as a make or break contact.
