Fast-acting fuse cutout links are Type K or N links that open within seconds of being exposed to overcurrent for protecting medium-voltage equipment such as capacitors and transformers. They are highly sensitive to changes in current flow and don't tolerate temporary overload currents or power surges.
Time-delay fuse cutout links are Type T links that tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. These slow-acting links coordinate with relays for line protection. They open to disconnect an electrical circuit when exposed to sustained loads and short circuits.
