+ DEHNguard® SE CI with integrated Backup Fuse

Modular surge arrester with integrated backup fuse

For protecting low-voltage consumer's installations against surges. For installation in conformity with the lightning protection zone concept at the boundaries from 0B– 1 and higher.
  • Arrester backup fuse integrated in the protection module
  • For use in case of higher rated voltages
  • Energy coordination with other arresters of the Red/Line product family
  • High discharge capacity
  • High reliability due to "Thermo Dynamic Control" SPD device monitoring
  • Easy replacement of protection modules without tools due to module locking system with module release button

Version

DEHNguard SE CI 440 FM: Modular single-pole surge arrester with integrated backup fuse (floating changeover contact)
DEHNguard SE CI WE 440 FM: Modular single-pole surge arrester with integrated backup fuse particularly for use in wind turbines (floating changeover contact)

Details

The modular surge arrester of the DEHNguard SE CI product family for systems with higher rated voltages of 400 / 690 V is available as type DG SE CI 440 FM and DG SE CI WE 440 FM. Type WE is equipped with a varistor of 750 V rated voltage and therefore is perfectly suited for converter operation with voltage peaks, for example in wind turbines.
With the already integrated arrester backup fuse the user no longer has to care about arrester-specific dimensioning requirements such as backup protection in the event of short-circuit and impulse current carrying capability.
Highest system availability even in case of higher voltages due to the ideal matching of SPD and integrated backup fuse. The integrated backup fuse has been developed especially for this case of application. It is not designed for continuous current but rather for impulse current and short-circuit protection which ensures optimal performance. The fuse only being tripped in case of end of SPD's service life, separate replacement is not necessary.
Due to the "Thermo Dynamic Control“ monitoring device, the surface temperature of the heavy-duty varistor and the intensity of the discharge current are used for evaluation. The operating state of each protective path is shown by means of a mechanical indicator with green and red indicator flags which needs no power to operate. It also indicates the activation of the "Thermo Dynamic-Control“ monitoring device and of the integrated arrester backup fuse.
In addition to this mechanical operating state / fault indication the versions of the DEHNguard SE CI (WE) 440 FM devices feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as break or make contact according to the particular circuit concept.
All benefits of the modular design of the DEHNguard family have been integrated into the new DEHNguard SE CI family.
The unique module locking system prevents the protection modules from becoming loose due to vibration during transport or the enormous forces of discharge.
The pluggable protection modules are mechanically coded which is an additional safety feature of these DEHN devices and ensures against installing an incorrect protection module.
