Eandrew — Back when building industrial-control panels, I subscribed to UL Standard 508. For 600V {and under} fuses in control panels, one 508 test was to "blow" them packed in surgical cotton, where success would yield no discoloration of the cotton. Molded-case thermal-magnetic breakers or motor-circuit protectors [and maybe insulated-case and air-frame versions] under the same conditions would cause the cotton to burst into flame. Id est, for that reason I agree with your opinion favoring modern fuses versus breakers.
