TJN200 - 200Amp Fuse

TJN200 - 200 Amp Fuse

The TJN200 is a 200 amp Class T fuse made for applications where fast protection matters. Designed with a very fast-acting response, it helps you protect electrical equipment from short circuits and high fault currents before serious damage can occur. With a 200 kA interrupting rating at 300 VAC, this fuse is commonly used in commercial and industrial power systems where reliable overcurrent protection is important. Its knife-blade style design provides a solid connection and makes installation straightforward. The compact size also makes it easier to fit into tighter electrical spaces without sacrificing performance. Because it is a current-limiting fuse, the TJN200 helps reduce the amount of energy that passes through during a fault condition, which can help protect connected equipment and lower repair costs.
