Littelfuse JLLN600P Class J Time-Delay Fuse 600A 300V

The Littelfuse JLLN600P is a Class J time-delay fuse rated for 600 amperes at 300 volts AC. This UL-listed fuse is designed for motor circuit protection and other applications requiring time-delay characteristics to handle temporary inrush currents without nuisance tripping.

Key Features:

• 600 ampere current rating for high-capacity circuit protection
• 300 volt AC rating suitable for commercial and industrial applications
• Class J design with current-limiting characteristics for enhanced safety
• Time-delay operation allows motor starting currents while protecting against overloads
• Plated contacts for reliable electrical connection and corrosion resistance
• Compact design fits standard Class J fuse clips and holders
• Interrupting rating of 200,000 amperes RMS symmetrical

Class J fuses are dimensionally designed to reject Class H fuses, ensuring proper current-limiting protection is maintained. Ideal for panelboards, motor control centers, and industrial equipment requiring reliable overcurrent protection.
