this depends on the application type where you are using
this circuit breaker. actually we will have to know whether
we require some delay in tripping after the overcurrent or a
frequent operation is needed. if a delay is needed and we
will have to bear some over temperature conditions then we
use thermal relay which has some delay and low trip current
at high temp. when we require the frequent operation then we
use magnetic type relay. also we will have to mind the
operating environment, nominal current rating and max peak
current bearing capacity and delay time of the circuit breaker.
