The 2807430000 from Weidmuller is a Single-Phase Surge Voltage Arrester that has been designed to efficiently minimize the possibility of interference coupling induced by transient surge voltages, even well below the limitations specified by the insulation coordination standards DIN VDE 0110-3 / EN 60664-3. It requires an input voltage of 230/400 V and can withstand a short-circuit current of up to 100 kA.

This surge suppressor is tested according to product standard IEC 61643-11 / DIN EN 61643-11 and can be installed in systems (e.g. power supply) as per IEC 61643-12 / VDE 0675-6-12 and IEC 62305-4 / VDE 0185-4 standards. It integrates a fuse into the arrester to enhance the protection capability. This surge suppressor is available in an IP20-rated DIN rail-mount package that measures 68 x 104.5 x 36 mm and is ideal for installation in power supply system applications.
