Fault tolerant system is an adjective to the whole system design. Circuit breaker is a library which lies inside your service, and when the circuit breaker manages all these things as Sajid mentioned in the blog, the system becomes more resilient and we can say that the system is handling failure with a fallback, not letting the failure to cascade and make the system turn into a waiting room, hence fault tolerant service.
