Littelfuse Class T fuses can be used in applications that require fastacting protection, such as equipment containing variable speed drives, rectifiers, and other surge-sensitive components. Main switches containing Class T fuses may be used to provide protection to individual electric services.
The small size of the fuses permits installation in panelboards and control centers for system upgrading when existing circuit breakers cannot safely interrupt larger available short-circuit currents.

Small, space-saving fuses provide a high degree of current limitation on short-circuits for excellent component protection.
