DS72R Type 2 AC Surge Protectors are used mainly for primary protection of single-phase networks at the main electricalpanel.
They provide common-mode protection (between the active conductors and protective wire) and are available in one-phase, single-phase.
The DS72R protector high impulse discharge capability classifies this SPD as re-inforced Type 2, useful in case of high lightning density areas. IEC60364 standard requests Type 2 SPD at the entrance of installation if the keraunic level Nk > 25.
The SPD is based on association of high energy varistors equipped with thermal disconnector and failure indicator, to comply with stan-dards. Version with a remote signaling for disconnection indication is also available (DS7*RS).
The DS72R is available for the main values of AC voltages.
The DS72R is DIN rail compatible and is built with a plug-in module (DSM70R-xxx) and a fixed base, which allows an easy and fastmaintenance
