Fuses
Protection of the Use semiconductor fuses with the tripping characteristic aR (VDE 0636-201 / DIN EN
devices 60269-2-1 / HD 630.2.1 54). In the event of a short circuit, these protect the mains rectifier
unit circuit on the input side against complete destruction, in order that it is possible to
repair the device.
Dimension suitable device protection fuses depending on peak current and the maximum
load integral i
