ORDERING INFORMATION
Littelfuse鈥檚 North American style square body semiconductor
fuses provide maximum flexibility in equipment design and
ultimate protection for today鈥檚 power conversion equipment.
Available in different body sizes and multiple mounting
styles, the broad range of ampere ratings allows great flexi-
bility in equipment design.
Engineered to provide state-of-the-art protection for SCR鈥檚,
diodes, thyristors, GTO鈥檚, and IGBT devices, Littelfuse
square body fuses have pure die-cut elements embedded in
solidified sand to control arcing and lower I
