Littelfuse L15S020 Semiconductor Fuse 20A Very Fast-Acting 150VAC 20000A@100VDC

Littelfuse's L15S Series offers advanced overcurrent protection with its highly reliable fuses, designed to interrupt extreme currents of up to 200,000 A.I.R., ensuring that both current interruptions and system requirements are well met. The extremely current-limiting design ensures low I²t and peak let-through currents, making it suitable for semiconductor applications where precision is essential. A fast-acting mechanism complements its performance, providing quick interruption to protect circuits from damage effectively. Recognized by Underwriters Laboratories, these fuses not only meet stringent safety standards but also serve as crucial supplemental protection for UL listed equipment, bringing confidence and reliability to industrial electrical applications.
