Compare MCB and fuse
MCB(Miniature Circuit Breakers) |
FUSE |
|
1
|
MCB trips off in case of excessive load.
|
Fuse melts/fuses in case of excessive load.
|
2
|
MCB is to be just put-on after correcting the
fault in wiring.
|
Fuse needs to be replaced with a new one.
|
3
|
Since we do not change the MCB, there is no risk
of putting on the MCB/switch even if the fault is not correctly repaired.
|
There is a risk of putting on the switch in case;
due to ignorance higher capacity fuse-wire is positioned.
|
4
|
Compact, small equipment.
|
Porcelain base and top. Not attractive.
|
5
|
Works on Bi-metal expansion or induced magnetism.
|
Works on melting/fusing due to high temperature.
|
6
|
Relatively costlier than fuse.
|
Relatively cheaper than MCB.
