Difference between Fuse and Circuit Breaker
Answer:
Fuse
Works on the thermal and electrical properties of the conducting materials
It doesn’t give any indication of overloads
Fuse can only be used once
Provides protection against power overloads
It detects and interrupts faulty circuit conditions
Low breaking capacity compared to the circuit breaker
Automatic operation
Operating time of fuse is 0.002 seconds
Low Cost
Circuit Breaker
Works on the switching principle and electromagnetism
It gives an indication of overloads
A circuit breaker can be used many numbers of times
Provides protection against power overloads and short circuits
It performs the interruption process only. Faults are detected by a relay system.
High breaking capacity
Can either be automatic or manually operated
Operating time of the circuit breaker is 0.02 – 0.05 seconds
High Cost
