Installation Sheet
The DS440 Type 2 surge protectors are compact devices designed to protect 3-phase+N 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 DS440 is DIN rail compatible and is built with a plug-in module and fixed base, which allows an easy and fast maintenance.
