25 Amp Fast-Acting Class T Power Fuse (600V)

Space-saving 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.

• Protection of individual electric services and meters.
• Main switches containing Class T fuses may be used to provide compact protection for meter stacks.
• 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.
• Series ratings up to 200,000 amperes are available.
