Branch protection circuit breakers

I was looking at the FAZ-NA line of circuit breakers by Eaton, and I was wondering if the capability of these to provide short-circuit interruption and thermal overcurrent protection removes the need of an overload relay. It seemed strange that these branch protectors were so much cheaper than other integrated motor circuit breakers, so I'd appreciate if anyone could share some information on the difference between the integrated branch protector and a motor protection circuit breaker.
