Description
Littelfuse 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
flexibility in equipment design.
Engineered to provide state-of-the-art protection for SCRs,
diodes, thyristors, GTOs, and IGBT devices, Littelfuse
square body fuses have pure die-cut elements embedded in
solidified sand to control arcing and lower I
2 t. All fuses are
also equipped with a blown fuse trip indicator.
Features
• Choice of mounting styles provides a wide choice for
equipment design.
• Broad range of ampere ratings in a given body size for
design flexibility.
• Very low I 2 t minimizes damage to protected components.
• Superior cycling ability for long, reliable life on high
cyclic loading.
• Extremely fast-acting and current-limiting for improved
protection to equipment.
Applications
Protection of rectifiers, inverters, DC drives, UPS systems,
reduced voltage motor starters, and other equipment in
globally accepted applications.
