TJN100 - 100Amp Fuse

TJN100 - 100 Amp Fuse

The TJN100 Class T fuse is built for one job—protecting your electrical equipment when fault currents hit hard and fast. Rated at 100 amps with a 200 kA interrupting capacity at 300VAC, this very fast-acting fuse helps stop damaging overcurrents before they have a chance to affect downstream components. In many electrical systems, speed matters. A fuse that reacts quickly can help reduce damage to drives, transformers, control panels, and other expensive equipment. The TJN100 is designed with current-limiting protection to help lower the amount of fault energy moving through the circuit during a short circuit or overload event. Its knife-blade style construction provides a solid connection and fits neatly into compatible fuse holders and assemblies. The compact size also makes it a good fit for tighter electrical spaces where larger protection devices may not work as easily. This fuse is commonly used in commercial and industrial applications where reliable protection and high interrupting capacity are important. From motor control centers to power distribution equipment, the TJN100 offers straightforward performance that maintenance teams and electricians can count on.
