The WSP440-230/G 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 surge protection devices is based on high energy varistor equipped with thermal disconnectors and failure indicator to comply with the necessary standards.
The WSP440-230/G is DIN rail compatible and is built with a plug-in module and fixed base, which allows an easy and fast maintenance.
