DEHNshield® ZP

Multipole combined arrester for primary power supply 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 + type 2 combined lightning current and surge arrester with spark gap technology
  • Energy-coordinated protection effect with regard to the terminal equipment (≤ 10 m) type 1 + type 2 + type 3
  • 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
  • Protects the entire electrical installation already near the infeed point
  • Operating state / fault indication by green / red indicator flag in the inspection window
  • No tripping of 32 A gG fuses up to short-circuit currents of 25 kArms
  • Fulfils the requirements on the lightning current discharge capacity according to IEC 60364-5-53**
  • Compact lightning equipotential bonding including protection of terminal equipment

Details

The DEHNshield ZP and DEHNshield ZP Basic combined 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 operating state / fault indication by green / red indicator flag in the inspection window of the device. Both due to this kind of operating state indication and their design as spark-gap-based arresters, DEHNshield ZP and DEHNshield ZP Basic arresters have no leakage and operating currents.
The proven DEHNshield 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. Undesired 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.
