TJS800 - 800Amp Fuse

TJS800 - 800 Amp Fuse

The TJS800 Class T Fuse is a solid choice for your protecting high-demand electrical systems where speed and reliability matter. Built for commercial and industrial applications, this 800 amp fuse reacts quickly during overloads and short circuits, helping reduce damage to connected equipment and keeping systems better protected when fault conditions happen. Its very fast-acting, current-limiting design is especially useful in facilities with sensitive electrical components or high available fault current.

With a 200 kA interrupting rating at 600 VAC, the TJS800 is designed to handle tough electrical environments often found in manufacturing plants, large commercial buildings, and heavy-duty power distribution systems. The compact knife-blade style construction helps simplify installation while maintaining a secure electrical connection. Because of its smaller footprint, it also works well in tighter panel layouts where space is limited.

Electrical contractors and maintenance teams often choose Class T fuses like the TJS800 for applications that need dependable short-circuit protection without unnecessary complexity. Its non-indicating design keeps things straightforward while still delivering the performance needed for demanding power systems.
