Description Littelfuse L_SQ Series High-Speed Square Body Style (Semiconductor) Fuses are specially designed for the protection of power semiconductor devices including diodes, triacs, IGBTs, SCRs, MOSFETs and other solid state devices that are typically designed into power conversion and conditioning equipment. Variable frequency drives, AC and DC drives, soft starters, power converters, and UPS equipment all utilize the extremely sensitive power semiconductor components that cannot withstand any line surge or overcurrent conditions.

Littelfuse POWR-SPEED™ products offer optimized circuit protection at the extremely fast speed required to protect modern day, sensitive, high-power semiconductor devices. Such products are commonly found in numerous applications including pulp and paper industries, cranes and heavy-lifting equipment, processing industries, wastewater treatment plants and various large factories and MRO facilities.

AC/DC Fuses • Class aR

Features • Extremely current limiting

• Low watt-loss design

• Compliance with US and Canadian requirements

• Class aR Performance according to IEC60269-4

• Direct bus-bar mount design

• Dedicated technical support
