TJN1200 - 1200 Amp Fuse

TJN1200 - 1200 Amp Fuse

The TJN1200 Class T fuse is a solid choice for your protecting high-amperage electrical systems where fast response matters. Rated for 1200 amps, this fuse is designed to react quickly during short circuits and overload conditions to help protect connected equipment from serious damage. Its current-limiting design helps cut down the amount of fault energy passing through the system, which can help reduce stress on electrical components and keep downtime to a minimum. Built with a knife-blade style connection, the TJN1200 fits securely into compatible equipment and works well in demanding commercial and industrial applications. Even with its high amp rating, the fuse maintains a compact size, making it easier to install in tighter spaces. With a 200 kA interrupting rating at 300 VAC, it’s made for systems where dependable overcurrent protection is critical.
