TJN175 - 175Amp Fuse

TJN175 - 175 Amp Fuse

The TJN175 Class T fuse is built for your electrical systems that can’t afford unnecessary downtime. Rated at 175 amps, this very fast-acting fuse helps protect equipment from damaging short circuits and overloads before they turn into larger problems. Its current-limiting design reduces the amount of fault energy that passes through the circuit, helping extend the life of connected components and improve overall system safety. With a compact knife-blade style body and a high interrupting rating of 200 kA at 300 VAC, the TJN175 is commonly used in commercial and industrial power distribution applications where dependable protection is critical. The smaller footprint also makes it a practical fit for tighter panel layouts and space-conscious installations.
