TJS45 - 45Amp Fuse Description

TJS45 - 45 Amp Class T Fuse

The TJS45 is a 45-amp Class T fuse made for fast protection in your electrical systems where high fault currents can cause serious damage. It’s a very fast-acting, current-limiting fuse designed to clear short circuits quickly and help protect connected equipment before problems spread through the system. With a 200 kA interrupting rating at 600 VAC, the TJS45 is commonly used in commercial and industrial power distribution applications that require dependable overcurrent protection in a compact size. Its cartridge-style body fits easily into compatible fuse holders and equipment with limited space. The non-indicating design keeps installation and replacement simple, while the fast response time makes it a good fit for systems with sensitive electrical components. The TJS45 is often used in control panels, motor circuits, UPS systems, and other equipment where reliable circuit protection is important for day-to-day operation.
