TJN25 - 25Amp Fuse

TJN25 - 25 Amp Fuse

The TJN25 Class T fuse is designed for your applications where fast protection is critical. Rated at 25 amps with a 200 kA interrupting capacity at 300 VAC, this very fast-acting fuse helps you to protect electrical systems and sensitive equipment from damaging overloads and short circuits before they become costly problems. Its compact cartridge-style design allows it to fit easily into tight spaces, making it a practical option for a wide range of commercial and industrial electrical setups. Because it’s a current-limiting Class T fuse, the TJN25 reacts quickly during fault conditions, helping reduce stress on connected components and improving overall system protection.

Unlike standard fuses, which may allow excess fault energy to pass through, the TJN25 is designed to respond rapidly to abnormal current conditions. That quick response can help extend the life of motors, transformers, panels, and other valuable electrical equipment. Its non-indicating design keeps the construction simple and dependable while still delivering the high-performance protection electrical professionals expect in demanding environments.
