Overvoltage protection devices SPD type 2 with the QuickSafe® thermal monitoring are designed for protection in indirect lightning effects and in switching overvoltages. They are built as close as possible to the feed point of the electrical system. All OVR T2 consist of a base part and an interchangeable protection module. They are equipped with a mechanical function display and the TS variants have a potential-free alternating contact. They are compatible with the System per M compact series and can be saved with them via phase rails. Main application in sub-distributions and end circuits.
