JLLN200 - 200Amp Fuse Description
JLLN200 - 200Amp Fuse
Engineered for demanding industrial and commercial installations, the JLLN200 fuse delivers dependable overcurrent protection for systems where safety and performance matter most. With a 200 A rating and up to 300 VAC (and 125 VDC) capacity, this compact Class T cartridge fuse is built to safeguard drives, transformers and electrical panels from short circuits and overloads. Its space‑saving design—approximately 2.44″ in length and just over 1 inch in diameter—allows reliable protection even in tight electrical enclosures. With fast‑acting current‑limiting characteristics and design pedigree from a leading manufacturer, the JLLN200 is an excellent choice for professionals seeking high‑quality circuit protection that won’t compromise on size or safety.
