What type of circuit breaker can be reset after tripping?

A reusable circuit breaker, also known as a resettable breaker, is designed to trip when it detects an overload or fault condition in an electrical circuit. After tripping, it can be reset either manually or automatically, allowing it to restore power without the need for replacement. This characteristic is crucial for maintaining electrical safety while providing convenience, as it eliminates the need for constant replacement of fuse elements that are typically used in traditional fuses.

In contrast, non-reusable circuit breakers indicate a permanent failure mode where after tripping, they cannot be reset and would need to be replaced. Manual circuit breakers, while they can be reset, are not characterized primarily as reusable because the term is more associated with those which can be reset automatically. Fuse circuit breakers, on the other hand, generally operate on the principle of melting a conductive element under overload, thus necessitating a complete replacement after tripping, which is not the case with a reusable circuit breaker. Therefore, the reusable circuit breaker is distinctly designed for multiple uses after resetting, making it the correct answer.
