Littelfuse JLLN200 Class T Fast-Acting Fuse 200A 300V Blade Terminal

The Littelfuse JLLN200 is a UL Class T fast-acting fuse designed to provide reliable overload and short circuit protection for non-inductive circuits and equipment. This Class T fuse features knife-blade-style construction with a 200 amp rating, making it ideal for high-current applications in industrial, commercial, and renewable energy systems.

Key Features:

• 200 amp current rating with 300 VAC and 125 VDC voltage ratings
• 200 kA AC and 20 kA DC interrupting capacity
• Compact cartridge design measuring 2.437 inches long by 1.062 inches diameter
• Blade terminal type for secure bolt mounting
• UL 248-15, CSA, and CE approved
• Space-saving design — less than one-third the size of comparable Class R fuses

When rated in accordance with the NEC, Class T fuses provide fast-acting overload and short circuit protection for electrical panels, distribution equipment, and power systems. These fuses are large enough to be bolted directly to terminals without requiring a separate fuse holder, simplifying installation in battery banks, inverters, and other high-current DC applications.

Common Applications: Inverter protection, battery bank overcurrent protection, commercial electrical panels, industrial machinery, and renewable energy systems.
