Littelfuse JLS090 Class J Time-Delay Fuse 90 Amp 600V AC

The Littelfuse JLS090 is a Class J time-delay fuse rated for 90 amps at 600 volts AC. Class J fuses are current-limiting, fast-acting fuses designed to provide superior short-circuit protection in commercial and industrial electrical systems.

Key Features:

• 90 amp rating at 600 volts AC
• Class J current-limiting design for enhanced equipment protection
• 200kA interrupting rating (AIR) for high fault current applications
• Time-delay characteristic allows temporary overloads while protecting against short circuits
• UL Listed and meets NEC requirements for Class J fuses
• Compact bolt-on design for space-efficient installation
• Non-renewable cartridge construction

Class J fuses are commonly used in motor control centers, panelboards, switchboards, and other commercial/industrial applications where superior short-circuit protection and current limitation are required. The time-delay feature makes them ideal for motor circuits and other applications with high inrush currents.
