Transcription

1 DEHshield Application-optimised multipole Application-optimised prewired combined lightning current based on spark gap technology simply equipped electrical installations with reduced technical requirements For protecting residential buildings and special applications (see brochure o. DS13) Discharge capacity up to 50 ka (10/350 μs) o tripping of 32 A g/gg fuses up to shortcircuit currents of 25 ka rms by indicator flag in the inspection window For protecting low-voltage consumer's installations against surges and even direct lightning strikes. For installation in conformity with the lightning protection zones concept at the boundaries from 0 A 2. DEHshield TC 255: Application-optimised for T-C systems DEHshield TS 255: Application-optimised for T-S systems DEHshield TT 255: Application-optimised for TT and T-S systems ("31" circuit) DEHshield T 255: Application-optimised for single-phase T systems DEHshield TT 2P 255: Application-optimised for single-phase TT and T systems ("11" circuit) The space-saving and application-optimised DEHshield family offers various benefits that are characteristic of spark-gap-based Type 1 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, DEHshield arresters are directly energy coordinated with other arresters of the Red/ine product family. Application-optimised DEHshield and surge arresters combine lightning equipotential bonding up to 50 ka (10/350 μs) lightning impulse currents and surge protection in a single device. This clearly distinguishes DEHshield 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, DEHshield 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. DEHshield 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 DS13. o 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 DEHventil. Fulfilling the most stringent technical requirements, DEHventil provides adequate protection at any time and is suitable for any application. The energy coordinated arresters even allow to protect terminal equipment if the distance between DEHshield and the consumers is 5 m. Owing to their non-exhausting spark gap and low space requirements, the application-optimised s 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 g/gg), meaning that upstream fuses are not tripped by mains follow currents. Busbars and pin-shaped terminals from DEH SÖHE can be used for connecting DEHshield to other DI rail mounted devices. The type designation of DEHshield allows to easily choose the right arrester for the relevant system configuration of the low-voltage consumer s installation. The operating state/fault indication of every protective path immediately provides information on the operating state of the arrester even if no operating current is present. 40
