Surge protection with a new design The multi-pole combined modular arresters for protection against lightning strikes and transient surge voltages now have an even more attractive design. In addition to their outstanding technical properties, they are pluggable and provide a clearly readable function control indication and status display. The variable installation position – the base part can be plugged in two directions – enables a flexible and cost-saving wiring. Easy setup, secure operation: n New: Easy changing of the protection module thanks to a twopart design with a...
