TJN500 - 500Amp Fuse

TJN500 - 500 Amp Fuse

The TJN500 Class T fuse is built for your electrical systems that need dependable high-speed protection against short circuits and overloads. With a 500 amp rating and a 200 kA interrupting capacity at 300VAC, this fuse is designed to react quickly when fault conditions occur, helping you to reduce damage to connected equipment and keeping downtime to a minimum. Its current-limiting design helps protect sensitive electrical components by reducing the amount of fault energy that passes through the circuit. This TJN series fuse features a knife-blade style construction for a secure fit in compatible fuse holders and disconnect equipment. The compact footprint also makes it a solid option for applications where panel space is limited. Because it is a non-indicating fuse, it maintains a clean, straightforward design commonly used in industrial and commercial power distribution systems. Whether it’s protecting motor control centers, transformers, panelboards, or other high-demand electrical equipment, the TJN500 delivers the fast response and high fault protection needed in critical power systems.
