Difference Between Fuse and Circuit Breaker

Fuse and Circuit Breakers are the protection devices. In this post, you’ll learn the difference between fuse and circuit breakers.

Fuse Circuit breaker
It is a single piece of wire which detects and interrupts the circuits on itself. A circuit breakers employes a relay which detects fault after which it operates.
Its breaking capacity is small. It has large breaking capacity.
It requires replacement after every operation. No replacement is required for most breakers.
Comparatively difficult to select. One might choose a wire of the wrong diameter which leads to inappropriate working and faults to equipment. There is no case of choosing wire, each breaker is properly labeled for the VA rating and there are little to no chance of a problem.
Inexpensive device. Expensive for the same ratings.
Its operating time is very small and has the ability to protect against surges that last for 0.002 seconds. Its operating time is comparatively large and is usually 0.1 or 0.2 seconds.
After every operation replacement is necessary due to which a delay in electric supply occurs. A circuit breaker simply trips and the delay in electric supply is for little to no time.
Can’t be used with GFCI’s. Can employ GFCI’s.
