Which one is better in low voltage distribution network in attitude of technical fuse or automatic switch?

Answer:

Deponds on the load that is under protection

if it is a3ph load such a induction motor so automatic switch is beter

else if some single phase load on the3ph network are supplied so fuse is beter

Fuses always better because of high sensitivity . but Circuit breakers are more easy operation , only you have to switch on again after clearing the fault.

 fuse  to check before make any new connection why it is gone

Fuse is better then automatic switch, because automatic switch can make malfunction but in fuse there is no chance to make mistake. Fuse is reliable then switch. If automatic switch make malfunction it will be very difficult in trouble shooting but in case of fuse you can save your time during trouble shooting .

It is depend on application, but the fuse is faster is some applications.
