However, uncontrolled and unprotected electricity is very dangerous. Power overloads and short circuits may cause equipment damage, and sometime fire and human casualties. The difference between the Relay and Circuit breaker is explained on the various factors like the their principle, working, type of device, usability etc.
The curve of the Circuit Breaker does not shift.
Principles of relay and circuit breaker operation.

The Fuse provides both detection and interruption process.

The circuit breaker is mainly used for protecting electrical circuits from the overflow of current so that the circuit is protected from damage.

What is the difference between contactors, motor starters, relays and circuit breakers ? These relays are referred to in the electrical power industry as . Power Circuit Breakers (PCB) break an electrical circuit to isolate faults. General introduction on protective relaying for power systems as well the operation principles of circuit breakers.
