TJN250 - 250Amp Fuse

TJN250 - 250 Amp Fuse

The TJN250 Class T fuse is designed for your electrical systems that need fast, dependable protection when fault currents occur. Rated at 250 amps with a 200 kA interrupting capacity at 300VAC, this fuse helps reduce damage to sensitive equipment by reacting quickly to overloads and short circuits. Its current-limiting design helps you to protect downstream components while supporting safer system operation in demanding commercial and industrial environments. Built with a knife-blade style construction, the TJN250 offers a secure fit for compatible fuse holders and disconnect applications. The compact body size also makes it a practical choice for crowded electrical panels and switchgear assemblies where space matters. Because it is a very fast-acting fuse, it is commonly used in applications where equipment protection is a higher priority than temporary overload tolerance.
