Answer / monty
Fristly understand
MCCB- module case circuit breaker & SFU- switch fuse unit
SFU- it is a combination of a fuse and isolator
MCCB-it is just like a MCB(miniature circuit breaker) but there is a small difference we can vary the range of MCCB means if you have 100A mvvb than you can use it for less than 100 A also but in MCB it is not possible so we can say that MCCB is a variable fuse.
