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.
