TJS80 - 80Amp Fuse

TJS80 - 80 Amp Fuse

The TJS80 Class T fuse is built for your applications where fast, dependable circuit protection is critical. Rated at 80 amps and capable of interrupting up to 200 kA at 600VAC, this current-limiting fuse helps you protect electrical systems and sensitive equipment from damaging overloads and short circuits. Its very fast-acting performance reacts quickly during fault conditions, helping reduce the risk of equipment damage and unnecessary downtime. The compact knife-blade design also makes it a practical fit for tight electrical enclosures and modern power distribution systems.

Because Class T fuses are commonly used for high-fault-current protection, the TJS80 is a solid choice for commercial and industrial electrical systems, including control panels, motor drives, transformers, and power distribution equipment. Its compact size and high interrupting capacity make it especially useful in applications where both space savings and reliable protection matter.
