Installation Sheet

DS70R type 2 AC surge protector are used mainly for primary protection of single and three-phase networks at the main electrical panel. They provide common-mode protection and are available in one-phase, single-phase, 3-phase and 3-phase+Neutral. This SPD is based on association of high energy varistors equipped with thermal disconnector and failure indicator, to comply with standards.

The DS70R surge protectors are designed to be used in a multipolar configuration to protect single-phase, 3-phase or 3-phase+N AC networks. Each pole of the SPD is connected between Line(s) and PE and Neutral and PE.
