- Time-delay, non-indicating UL Class H fuses have a 10kA interrupting rating (IR) for general purpose use in existing installations where a small-interrupt, slow-blow fuse is needed
- They're sometimes used in place of Class K5 fuses to downgrade from a current-limiting system
- These renewable fuses have a fusible link that can be replaced after the fuse blows to allow reuse
- They tolerate temporary inrush currents without opening, which prevents nuisance-blowing from equipment startups
- They open to disconnect an electrical circuit when exposed to sustained loads and short circuits
