The DS2x0-xxDC surge protector is designed to protect equipment connected to a DC power supply (or AC) against lightning surges. These devices are based on high energy varistors (MOV) matched with the DC operating voltage (from 12 to 350 VDC. The MOV are equipped with internal thermal disconnectors in order to provide safe end of life. The indication of the disconnection status is provided by a mechanical indicator and is transmitted through a remote signal mechanism. The pluggable module allows an easy and fast maintenance.

The DS2x0-xxDC is DIN rail compatible and is connected in parallel on the DC line to be protected.
