The 2827580000 from Weidmuller is a Single-Phase Surge Voltage Arrester that has been designed to effectively reduce the interference coupling that can occur due to transient surge voltage levels, even significantly below the limits prescribed by insulation coordination according to EN 60664-3/DIN VDE 0110-3. It has a voltage rating (AC) of 230 V and a current rating of up to 40 kA. This arrester can be installed in power supply systems and has been tested according to IEC 61643-11/DIN EN 61643-11. It consists of a built-in fuse and therefore, does not require a separate fuse, simplifying the protection mechanism and design. This surge arrester is available in an IP20-rated DIN rail-mount package that measures 68 x 76 x 111 mm.
