TJS400 - 400Amp Fuse Description
TJS400 - 400 Amp Fuse
The TJS400 is a 400 amp Class T fuse designed for fast protection in your electrical systems where high fault currents are a concern. With a 200 kA interrupting rating at 600VAC, it helps stop dangerous short circuits quickly before they can damage connected equipment. Its very fast-acting design makes it a good fit for protecting sensitive components and high-demand power systems. This fuse uses a knife-blade style connection for a secure fit and reliable performance in commercial and industrial applications. The compact body size also helps when working in panels or equipment where space is limited. Because it is a current-limiting fuse, the TJS400 helps reduce the amount of fault energy that moves through the circuit during an electrical event. The non-indicating design keeps the fuse simple and dependable for everyday use in power distribution equipment, control panels, switchgear, and other heavy electrical systems.
