TJN800 - 800Amp Fuse

TJN800 - 800 Amp Fuse

The TJN800 is a Class T current-limiting fuse designed for high-amperage electrical protection in your commercial and industrial systems. With an 800 A rating and a 200 kA interrupting capacity at 300V AC, this fuse is built to respond quickly to overloads and short circuits, helping protect connected equipment from costly damage. Its very fast-acting design makes it a solid option for applications where sensitive electrical components need dependable fault protection. The compact knife-blade style body allows the TJN800 to fit into tighter electrical setups without sacrificing performance. Because it’s a non-indicating fuse, it works well in systems where simple, reliable overcurrent protection is the priority. It’s commonly used in switchboards, control panels, motor circuits, and other power distribution equipment where high fault current may be present.
