Fuses and circuit breakers have a similar purpose of interrupting electrical flow, but they work in different ways. A fuse is made up of a metal element that melts when it's exposed to excessive heat. On the other hand, a circuit breaker uses a switch mechanism that triggers when it detects an electrical overload.
Major factors include current and voltage ratings, type of protection, number of poles, mounting style, compatibility, size, environmental conditions and quality.
