Installation Sheet
The DS240 Type 2 surge protectors are compact devices designed to protect single phase networks at the main switchboard. They provide a common or common/differential mode protection.
This SPD is based on high energy varistor equipped with thermal disconnectors and failure indicator to comply with standards. The DS240 is DIN rail compatible and is built with a plug-in module and fixed base, which allows an easy and fast maintenance.
