  • Amperage: 200 A
  • Voltage: 125 V, 300 V
Space saving POWR-GARD Class T fuses are the most compact fuses available in ratings above 30 amperes — less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection. For motor and general purpose circuits where space is not critical, we recommend POWR-PRO™ JTD_ID Indicator series, LLNRK/LLSRK series, or FLSR_ID Indicator series.

  • Applications
    • Series ratings up to 200,000 amperes are available.
    • Molded case circuit breaker load centers and panelboards have increased interrupting ratings when “series rated” with Littelfuse Class T fuses. Refer to panelboard manufacturers’ literature for UL Listed combination of fuses and panelboards.
    • Protection of individual electric services and meters.
    • Main switches containing Class T fuses may be used to provide compact protection for meter stacks.
  • Space Saving
    • Typical three-pole Class T fuse blocks require less than 50% of the panel area required for Class R fuse blocks. Switch enclosures, fuse pullouts, and other equipment using Class T fuses are often correspondingly more compact.
  • Longer Equipment Life
    • Current limiting design greatly reduces damage to equipment caused by heating and magnetic effects of short circuit currents.
  • Economical
    • Extremely current limiting design often permits use of readily available, less costly equipment.
    • Used as input or output fuses for surge-sensitive components, such as variable speed drives and rectifiers, fast-acting Class T JLLN/JLLS fuses may prevent opening of expensive semiconductor fuses protecting individual components.
  • Safety
    • 200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes.
    • Extremely current limiting — Stops damaging short circuit current faster than any mechanical protective device.
    • Fast-Acting — Provides fast-acting overload protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components.
