Table 3.3 Recommended mains fuses
Table 3.3: Semiconductor protection only, lines are not reliably protected
CAUTION
Devices of sizes C and E require semiconductor protection fuses in the network incoming line to protect the
semiconductors according to Table 3.3. For devices with integrated arm-circuit fuses (sizes H and K – see
Table 3.5), no semiconductor protection is required outside the device.
Line protection must be ensured for all device types by assigning a suitable line protection element (e.g. fuse,
line protection circuit-breaker) to the line cross-sectional area as defined in the currently valid standards – e.g.
DIN VDE 0100 Part 430.
