Yes...more so to protect the branch circuit, with a regular circuit breaker is actually proceeding the branches. Think of this being a power strip...bunch of outlets, with a circuit breaker, but I want to limit the potential current draw down each branch to each outlet, so I can use 18AWG wiring. The main feed breaker will provide the short circuit protection for the entire set of branch circuits.

Note that the interrupting capacity of those things is only 40A (!), compared to perhaps 10,000 A on a regular fuse. Is this just for overload (not fault) conditions? Suggest you check carefully into the limitations of the UL 1434 rating, such as "... are not intended to replace current interrupting devices such as fuses, but are intended to provide a level of overcurrent protection" Best regards, Spehro Pefhany -- "it's the network..."
