DEHNventil® ZP

Multipole Combined Lightning Current and Surge Arrester for Primary Power Systems

For protecting low-voltage consumer's installations against surges and even direct lightning strikes. For installation in conformity with the lightning protection zone concept at the boundaries from 0A– 2.
  • Type 1 and type 2 combined lightning current and surge arrester with RADAX Flow spark gap technology
  • Fully compliant with all requirements of the national VDN* guideline on the use of SPDs upstream of the meter panel
  • Quick and easy installation by snapping the arrester onto 40 mm busbar systems
  • Test for correct operation by pressing the button with indicator light
  • No tripping of 32 A gG fuses up to short-circuit currents of 25 kArms
  • Discharge capacity up to 100 kA (10/350 µs)
  • Capable of protecting terminal equipment
  • Maximum system availability

DEHNventil ZP TNC 255: Three-pole combined lightning current and surge arrester for TN-C systems for use in primary power systems in case of buildings with external lightning protection system and high performance parameters
DEHNventil ZP TT 255: Four-pole combined lightning current and surge arrester for TT and TN-S systems for use in primary power systems in case of buildings with external lightning protection system and high performance parameters

Details

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 device parameters and design are fully compliant with all requirements of the German VDN guideline* on the use of surge protective devices in primary power systems.
