DEHN SÖHNE GmbH Co.KG. products

Protection of terminal equipment with wave breaker function: The lightning impulse is reduced to a minimum so that terminal equipment is subjected to almost no energetic stress. DEHNshield ... (FM) takes up only 4 standard DIN modules and is thus ideally suited for DIN rails with restricted space conditions. The combined arrester is available with remote signalling contact and can thus be monitored through your factory master control system. This ensures that faults are identified at an early stage and that they are quickly eliminated.

Protect employees, limit overvoltages, prevent AC corrosion. The decoupler DASD provides protection against transient, temporary and long-duration overvoltages.

Flexible and space-saving surge protective device. The DEHNcord type 2 surge arrester (two-pole, single-pole) can be installed in installation systems such as the terminal compartments of end loads, cable ducts or flush-mounted systems. The new DEHNcord surge arrester from the globally active lightning and surge protection expert DEHN, reliably protects for example outdoor LED lights from surges caused by lightning interference.

Type 1 + type 2 combined arrester with SCI technology. Protect your solar power system against lightning and surge damage by means of the DEHNcombo YPV SCI combined arrester.

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 spark-gap-based protection modules of the modular DEHNventil series combine safety and innovation in a single device. Apart from the encapsulated RADAX Flow spark gap technology, the compact protection modules incorporate the complete monitoring circuit for controlling the energy flow of the spark gap, the monitoring device and the operating state / fault indicator.

DEHNventil ZP combined lightning current and surge arresters are specifically designed for installation in the busbar connection panels of meter panels. They can be directly snapped onto the busbar system without tools. Their compact dimensions leave enough space for the connecting cable from the service entrance box, even if two selective main circuit breakers are installed.The operating state of the arresters is indicated by an indicator light at the push of a button. Both due to this kind of operating state indication and their design as a spark-gap-based arrester, DEHNventil ZP arresters have no leakage and operating currents.The RADAX Flow spark gap technology ensures that fuses are not tripped by follow currents even in case of low-current-rated fuses in the service entrance box. Undesirable supply interruptions due to tripped main fuses are thus avoided.

The combined lightning current and surge arresters of the BLITZDUCTORconnect series are designed for universal use and system protection in industrial environments, at information technology signal interfaces, and in the field of automation or measuring and control technology:

Two-pole arrester base for installation on printed circuit boards by means of soldering process for BLITZDUCTORconnect modules. With integrated remote signalling contact (floating changeover contact) for the condition monitoring of the protection modules.

Prewired spark-gap-based type 1 and type 2 combined lightning current and surge arrester consisting of a base part and plug-in protection modules. Maximum system availability due to RADAX Flow follow current limitation. No tripping of 20 A gG fuses up to short-circuit currents of 50 kArms. Discharge capacity up to 100 kA (10/350 µs). Capable of protecting terminal equipment. Operating state / fault indication by green / red indicator flag in the inspection window. Easy replacement of protection modules without tools due to module locking system with module release button. Vibration and shock-tested according to EN 60068-2.
