Dehnventil lightning current surge arrestors

October 2010 Electrical Power & Protection

Dehn’s Dehnventil lightning current surge arresters combine safety and innovation in a single stage modular design for use in compact electrical installations. By using the double terminals the surge arresters can be connected in series up to nominal currents of 125 A, as preferred by IEC 60364-5-53.

The functional design of this red/line product family features a base part and plug in protection module held in place by a button release for easy removal and replacement without tools. The operating status can be seen visually via a red/green indicator or transmitted for remote processing using the signalling changeover contact. Encapsulated discharge spark gaps and the small space required by the combined lightning current and surge arresters allow for easy integration into switchgear installations or distribution boards for high availability of the electrical installation to be protected.

Dehnventil M TT can be used in all systems such as TN-S, TNCS and TT.
