ORDERING INFORMATION
Littelfuse’s North American style square body semiconductor
fuses provide maximum flexibility in equipment design and
ultimate protection for today’s 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’s,
diodes, thyristors, GTO’s, and IGBT devices, Littelfuse
square body fuses have pure die-cut elements embedded in
solidified sand to control arcing and lower I²t. All fuses are
also equipped with a blown fuse trip indicator.
FEATURES
I Choice of mounting styles provides a wide choice for
equipment design.
I Broad range of ampere ratings in a given body size for
design flexibility.
I Very low I²t minimizes damage to protected components.
I Superior cycling ability for long, reliable life on high
cyclic loading.
I Extremely fast-acting and current limiting for improved
protection to equipment.
