mcb - basically used for domestic and Industrial
application very near to load end and rating not exceeding
100A and have a short circuit rating upto 18 KA.It uses
thermal trippin mechanism for protecting the load.
on the other end MCCB basically used in industrial
Application is more sensitive than MCB.ITs available from
10A to 2000A and Short circuit ratio from 10 KA to 200KA.IT
have both thermal and magnetic tripping function and
basically more sensitive than MCB.
