TJN20 - 20Amp Fuse

TJN20 - 20 Amp Fuse

The TJN20 is a 20-amp Class T fuse designed for fast, reliable protection in your electrical systems where downtime and equipment damage can become costly problems. This very fast-acting fuse is designed to clear fault currents quickly, helping you to protect sensitive components before excess current has a chance to travel through the system. Its current-limiting design also helps reduce the energy released during a short circuit, which can extend the life of connected equipment. With a compact cartridge-style body and a high interrupting rating of 200 kA at 300 VAC, the TJN20 is often used in industrial and commercial applications where dependable overcurrent protection is important.
