The interrupting rating is an important safety feature of fuses that must be clearly marked, especially if it differs from the standard rating of 10,000 amperes. The other options (material capacity, date of manufacture, and current-limiting) are also important information, but they are not as critical as the interrupting rating for ensuring proper fuse selection and operation.
