Resettable Circuit Breaker – How Does It Work

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.

Here at JTS we use Resettable Circuit Breakers in our Power Easy Dual Battery Systems. They are reliable and protect the system from short circuits.

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.
