TJS450 - 450Amp Fuse

TJS450 - 450 Amp Fuse

The TJS450 Class T fuse is made for your electrical systems that need quick response protection during overloads and short circuits. With a 450 amp rating and a 200 kA interrupting rating at 600VAC, this fuse is a solid choice for commercial and industrial power systems where dependable circuit protection is important. Its very fast-acting design helps clear fault conditions quickly, which can help you reduce damage to connected equipment. The current-limiting construction also helps control the amount of fault energy passing through the circuit. That makes the TJS450 a good fit for protecting sensitive electrical components, distribution equipment, and high-demand systems. The knife-blade style body allows for secure installation, while the compact size works well in tighter electrical enclosures and panel layouts. Because it uses a non-indicating design, there are fewer components while still delivering reliable performance in everyday applications. The TJS450 is commonly used in switchboards, panelboards, motor control centers, and other power distribution equipment where high interrupting capacity and fast protection are needed.
