Littelfuse JLS020 20A Fast-Acting Class J Fuse 600V

The Littelfuse JLS020 is a 20-amp fast-acting Class J fuse designed for reliable overcurrent protection in commercial and industrial electrical systems. Rated for 600 volts AC, this current-limiting fuse provides superior protection for conductors, controls, and equipment in low-voltage power distribution applications.

Key Features:

• 20-amp current rating with 600VAC voltage rating
• Fast-acting response for sensitive equipment protection
• Class J design with bolt-on or clip mounting options
• Current-limiting technology reduces potential damage during fault conditions
• High interrupting rating of 200,000 amps AC
• UL Listed and CSA certified for North American installations
• Dimensional rejection feature prevents incorrect fuse replacement

Class J fuses are commonly used in lighting panels, control panels, motor control centers, and other commercial/industrial applications where space is limited and reliable overcurrent protection is essential. The fast-acting characteristic makes this fuse ideal for protecting solid-state devices and other equipment sensitive to short-circuit currents.
