Listed current-limiting fuses have which of the following features to prevent incorrect installations?

Listed current-limiting fuses are designed with physical size rejection features to help prevent incorrect installations. This means that the fuses are manufactured in such a way that they can only fit in specific fuse holders that are compatible with their size and rating. This physical dimension is crucial because it ensures that only the correctly rated fuse can be used in a given application, thereby promoting safety and compliance with electrical codes.

When a fuse is installed in an incorrect holder or is of an incompatible size, it may not perform its intended protective function. The physical size rejection feature effectively prevents this risk by limiting the options for installation to only those that are appropriate for the specific fuse type and its intended service. This design consideration is vital in electrical installations to avoid issues such as equipment damage, electrical fires, or unsafe operating conditions.

The other options relate to other characteristics of fuses but do not specifically address the prevention of incorrect installations in the same direct manner as physical size rejection.
