Catalog Numbers (amps)

• Small, space-saving fuses provide a high degree of current

limitation on short-circuits for excellent component

protection

• Commonly applied in electric heat circuits, load center,

disconnect switches, and meters

• The small size of the JJN Class T fuses permits installation

in panelboards and control centers for system upgrading

when existing circuit breakers cannot safely interrupt larger

available short-circuit currents
