UL Class T Fuses
Available4 products
UL Class T fuses are very small fuses that require minimal installation space for protecting electrical feeders and branch circuits from overcurrent. These fuses have an interrupting rating (IR) of 200kA and are not interchangeable with any other UL fuse class. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.
Series
Time-Delay UL Class T Fuses, Nonindicating
Time-delay, nonindicating UL Class T fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class T fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have no indicator for identifying a blown fuse, so they're sometimes used with an indicating fuse block or cover.
