The item on the left will not clear any faults as it is only a mechanical adapter. I'm not sure what the device on the right is. The other 2 are fuses and will clear overcurrents and overloads based on their rating.
Are you trying to tell us that fuses are not a reliable method of clearing overloads and overcurrents? Have you ever found a breaker that wouldn't trip? How about a fuse that wouldn't blow? In my opinion a fuse is a more reliable OCPD than the thermal magnetic device that we normally use. Are they subject to tampering? Sure, but with so many breakers being of the plug in type, they both are too often replaced with one of a size larger than permitted by the code. The type S adapter makes it harder to tamper with a type S fuse than it is to tamper with a circuit breaker.
As far as clearing an arc fault, they will only do this if and when the current produces enough heat to exceed the melt point of the fuse element.
