Description

This DEHN AC Surge Arrester – Type 1 – 3 Phase combined lightning current and surge arrester is for three phase systems.   This 4 DIN rail mounted type 1 and 2 combined lightning and surge arrester is for grid AC connections. It is to be used when the installation has a fitted lightning protection system on TNS supply systems. It will need to be fitted at the origin of the supply with type 2 SPD closer to the inverter. This arrester meets the requirements of BS7671 Amendment 1 section 534.

The space-saving and application-optimised DEHN AC Surge Arrester – Type 1 – 3 Phase family offers various benefits provided by type 1 and type 2 spark-gap-based arresters such as the “wave breaker function” (WBF). This function and the associated reduction of the pulse time mitigate the energy of the lightning impulse current to an acceptable level for downstream protection stages or terminal equipment. Moreover, DEHNshield arresters are directly energy coordinated with other arresters of the Red/Line product family.

Application-optimised DEHNshield combined lightning current and surge arresters combine lightning equipotential bonding up to lightning impulse currents of 50 kA (10/350 µs) and surge protection in a single device. This clearly distinguishes DEHNshield from varistor-based arresters of this application and performance class.

Due to their technical parameters, which are rated for use in simple and compact electrical installations, DEHNshield arresters are ideally suited for this application class. For this reason, they are a space-saving and application-optimised solution in particular for residential buildings.

DEHN AC Surge Arrester – Type 1 – 3 Phase arresters also provide optimal protection in buildings without external lightning protection system where roof superstructures or overhead line supplies are installed. According to VdS 2031, it is advisable to use type 1 SPDs for these buildings. A detailed application description can be found in brochure DS193. No additional backup fuse is required if an installation is protected by backup fuses up to 160 A. If applications are not sufficiently defined, it is advisable to use DEHNventil. Fulfilling the most stringent technical requirements, DEHNventil provides sufficient protection at any time and is suitable for any application. The energy-coordinated arresters even allow to protect terminal equipment if the distance between DEHNshield and the loads is ≤ 5 m. Owing to their spark gap without venting means and low space requirements, application-optimised combined lightning current and surge arresters can be easily integrated into distribution boards. The follow-current-limiting spark gap technology ensures selectivity even in case of low-value fuses (35 A gL/gG), meaning that upstream fuses are not tripped by mains follow currents.

Busbars and pin-shaped terminals from DEHN + SÖHNE can be used for connecting DEHNshield to other DIN rail mounted devices. The type designation of DEHNshield allows to easily choose the right arrester for the relevant system configuration of the low-voltage consumer’s installation.
The operating state / fault indicator of every protective path needs no power to operate and immediately shows the operating state of the arrester.

Due to their parameters and design, the DEHN AC Surge Arrester – Type 1 – 3 Phase devices can be installed even upstream of meter panels in low-voltage consumer’s installations.
