[font=times]NEMA Reaffirms FU 1-2002 Low Voltage Cartridge Fuses [/font]
[font=times][color=#708090]Rosslyn, Va.—The National Electrical Manufacturers Association (NEMA) has reaffirmed FU 1-2002 Low Voltage Cartridge Fuses.
FU 1-2002 (R2007) covers eight classes of low voltage cartridge fuses — fuses consisting of a current responsive element inside a fuse body with contacts on both ends — rated 600 volts or less, alternating current, and direct current. The eight classes of fuses covered are G, H, J, K, L, R, T, and CC. This standard includes updates to the definitions, voltage rating and interrupting rating tables, and the current carrying and temperature rise tests.
