• 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.
