Circuit breaker is the device such as ACB's or MCCB's which
trips the entire system if there is a failure. By the entire
system we mean the elements connected to the particular
busbar of that crcuit breaker.
An isolator is used to cut out a portion of a substation
when a fault has occured on a particular portion of the
whole station to rectify it and repair it and in the
meanwhile the other devices operatee without being affected
by the faulty part.
