Surge protection PU II 2 280V / 40kA
The Weidmüller type PU II surge protector protects installations for low-voltage consumers and electronic equipment against overvoltages that can occur due to atmospheric discharges (thunderstorms) or switching (transients).
The PU-II series meets the requirements of classes II and III according to IEC 61643-1: 2008 and those of type 2 and type 3 according to EN 61643-111, class C and D and DIN VDE 0675 , T. 6, class C and D, T. 6, A2 10/96.
Operation, maintenance and approval checks
The building blocks of the PU-II surge protector are tested by means of a visual inspection. The signaling is controlled by a thermal interruption. If this is activated, and therefore there is no protection anymore, the color in the display changes from green to red. A diverter that is no longer functioning can be replaced by a professional without loosening the wiring. The pluggable varistor modules are coded according to their voltage. Only the matching replacement varistor can therefore be inserted.
