LittelFuse LA120URD71LLI0550 VERY FAST-ACTING SEMICONDUCTOR FUSE Amperage: 550 Voltage: 1200 VAC

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 flexibility 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 l2t. 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 l2t 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.
