TJS500 - 500Amp Fuse

TJS500 - 500 Amp Fuse

The TJS500 Class T Fuse is built for your electrical systems that need fast, dependable protection against damaging overloads and short circuits. With a 500 A rating and a 200 kA interrupting capacity at 600 VAC, this fuse is designed to react quickly when fault conditions occur, helping protect valuable equipment and reduce the risk of costly downtime. Its compact knife-blade design makes installation easier in tighter spaces often found in commercial and industrial electrical equipment.

Because it’s a very fast-acting, current-limiting Class T fuse, the TJS500 helps reduce the amount of energy that passes through during a fault event. That added protection can make a real difference when safeguarding transformers, panelboards, motor control centers, and other sensitive power distribution components. The non-indicating design keeps things straightforward while delivering the high-performance protection expected in demanding environments.
