DEHNguard SE H ... FM

Single-pole Surge Arrester with "Lifetime Indication“

Single-pole surge arrester for protecting low-voltage consumer's installations from surges. For installation in conformity with the lightning protection zone concept at the boundaries from 0B– 1 and higher.
  • Universal surge arrester comprising a base part and a plug-in protection module
  • Energy coordination with other arresters of the Red/Line product family
  • High discharge capacity
  • High reliability due to "Thermo Dynamic Control" SPD monitoring device
  • Easy replacement of protection modules without tools due to module locking system with module release button

Version

DEHNguard SE H 1000 FM: Pluggable single-pole surge arrester with a high discharge capacity comprising a base part and a plug-in protection module; with remote signalling contact for monitoring unit (floating changeover contact)
DEHNguard SE H 1000 VA FM: Pluggable single-pole surge arrester with a high discharge capacity and a varistor connected in series with a spark gap comprising a base part and a plug-in protection module; with remote signalling contact for monitoring unit (floating changeover contact)

Details

DEHNguard SE H 1000 FM is a powerful type 2 arrester specifically designed for higher system voltages and higher discharge currents. This arrester is universally applicable due to its low voltage protection level and its design as single-pole device.
DEHNguard SE H 1000 VA FM is a powerful type 2 arrester specifically designed for higher system voltages and higher discharge currents. Thanks to the high nominal voltage and the series connection of a varistor and a gas discharge tube, it is ideally suited for wind turbines (rotor and inverter) and for other applications such as PV systems, railways or cable cars with higher voltages where no leakage current may be present.
All necessary components such as earthing clips EB 1 ... 1.5 with a width of 1.5 standard DIN modules are available as accessory to ensure the correct connection for the relevant system configuration as per IEC 60364-5-53.
The the arresters feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.
