Isolation Link

• The isolation link is used in series with Bay-O-Net fuse link to provide extra protection for transformer. Isolation links are not fuses and do not have an interrupting rating. During a low impedance transformer failure, the isolation link will melt so that the opened primary circuit of a failed transformer cannot be re-energized by the utility line crew.
• The design of the isolation link protects the link element from handling damage that can cause nuisance open circuits inside the transformer.
• The isolation links are designed to be bolted directly to the lower connection tab of the Bay-O-Net fuse holder in series between the primary transformer bushing and primary coil.
