TJN300 - 300Amp Fuse

TJN300 - 300 Amp Fuse

The TJN300 is a 300-amp Class T fuse designed for your fast protection in electrical systems that need to handle high fault currents safely. With a 200 kA interrupting rating at 300VAC, it helps you to stop damaging short circuits quickly before they can affect connected equipment. Its very fast-acting, current-limiting design makes it a practical choice for protecting sensitive electrical components in commercial and industrial applications. This fuse uses a knife-blade style design for a secure fit in compatible equipment. Its compact size also makes it easier to install in panels, switchboards, and other tight electrical spaces. The non-indicating body keeps the design simple while still delivering the high-performance protection Class T fuses are known for.
