Table 3.2 Recommended mains fuses
Column 1: This fuse with gR characteristic protects the semiconductors. At the same time, they also have
line protection characteristic which can be used if the appropriate conductor cross-sections are
chosen, e.g. in accordance with DIN VDE 0100 Part 430 (to be applied for preference).
Column 2, 3: Semiconductor protection only, lines are not reliably protected. Discriminative line protection is
assured only by correlating the line protection fuses to the installed conductor cross-section in
accordance with the applicable regulations - e.g. DIN VDE 0100 Part 430.
