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.

Answer / dev
