Description

The DEHNguard SU/MU product family are Type 2 surge protection devices (SPD) that are designed for all common North American electrical power systems. These SPDs, from DEHN, are UL 1449 4rd edition approved with a 200 kA SCCR rating and do not need any additional over-current protection.

Varistor Based Protection Modules

Varistor based protection module for DEHNguard M, DEHNguard S, DEHNgap C S surge arresters.

  • high discharge capacity due to heavy-duty zinc oxide varistors / spark gaps
  • easy replacement of protection modules without tools due to module locking system with module release button
  • the plug-in protection module can be replaced without switching off the mains voltage and without removing the distribution board cover
