Littelfuse fuse, JLLN, 300A, 300 VDC

JLLN fuses are less than one-third the size of comparable class R fuses and are typically used for short circuit protection of drives and surge sensitive components. When rated in accordance with the NEC, JLLN fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment.

Applications

• Protection of individual electric services and meters
• Main switches containing class T fuses may be used to provide compact protection for meter stacks

Features

• 200 kA interrupting rating: Reliable interruption of all overcurrents up to 200 000 amperes
• Extremely current limiting: Stops damaging short circuit current faster than any mechanical protective device
• Fast-acting: Provides fast-acting overload protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components
• Compact design
