Details

With their functional Red/Line design, the devices of the modular DEHNventil family provide a combination of safety and innovation. Designed for "all-in-one installation", the arresters integrate lightning equipotential bonding and surge protection in a single device, making them ideal for use in compact electrical installations. The energy-coordinated arresters even allow to protect terminal equipment if the distance between DEHNventil and the loads is ≤ 10 m. With a lightning current discharge capacity up to 100,000 A, the arresters ensure a high degree of availability of the electrical installation to be protected. Even in large-scale electrical installations, the modular DEHNventil arresters provide various application benefits. The Red/Line surge arresters installed at the boundaries of the individual lightning protection zones, for example, are already energy-coordinated with the DEHNventil arresters. Encapsulated creepage discharge spark gaps and the small space requirements enable easy integration into switchgear installations or distribution boards. A special feature of the modular DEHNventil family is its functional design, in particular the module locking system. It fixes the protection module firmly in place so that it is safely connected to the base part even with maximum loads. If a protection module has to be replaced, it releases the module without tools and allows easy removal. By using the double terminals suitable for all conductors, the arresters can be connected in series in a space-saving and cost-effective way up to nominal currents of 125 A as preferred by IEC 60364-5-53. Busbars of type MVS 3 8 6 and MVS 4 11 8 can be used for connecting further DIN rail mounted devices. The type designation of DEHNventil arresters allows to easily choose the right arrester for the relevant system configuration of the low-voltage consumer’s installation.

The patented RADAX Flow technology for follow current limitation and extinction allows high availability of the electrical consumer's installation to be protected. Even in case of short-circuit currents as high as 100 kArms, mains follow currents are reduced in such a way that selectivity with respect to low-current-rated fuses is ensured. This means that upstream fuses will not trip due to upcoming mains follow currents.

The operating state / fault indicator of each protective path needs no power to operate and instantly shows the operating state of the surge arrester. Apart from the standard visual indicator with green and red indicator flags, DEHNventil M ... FM devices feature 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.

Due to their parameters and design, the devices can be even installed upstream of meter panels in low-voltage consumer's installations.
