? Small, space-saving fuses provide a high degree of currentlimitation on short-circuits for excellent component protection. ? Commonly applied in electric heat circuits, load center, disconnect switches, and meters. ? The small size of the T-Tron fuses permits installation in panelboards and control centers for system upgrading when existing circuit breakers cannot safely interrupt larger available short-circuit currents. ? High speed of response for semiconductor protection. ? Available for printed circuit board applications.

See page 2 0f 2 for printed circuit board variations.

Recommended fuseblocks for Class T 600V fuses See Data Sheet: 1116
