In this video Rowan talks about how a Resettable Circuit Breaker works. Resettable Circuit Breakers are useful for many applications but can have problems. When they fail, it is not obvious that they have failed. A midi fuse is easy to see if it has blown, unlike a resettable circuit breaker.
A resettable circuit breaker is an electronic component used to protect against over-current.
The advantage of the fuse resetting automatically means that you don’t need to replace a fuse every time.
Prolonged overcurrent situations will eventually cause the fuse to fail.
