DOIII isolation links provide extra protection during refusing and switching operations when used in series with a DO-III type fuse.
Isolation links are not fuses and do not have an interrupting rating. During a transformer failure, the isolation link will melt so that the opened primary circuit of a faulted transformer cannot be re-energized by the line crew. ABB isolation links are fully interchangeable with links of other manufacturers.
