TR9R - 9 Amp Fuse

TR9R - 9 Amp Fuse

The TR9R 9 Amp Class R Fuse is a smart choice for your protecting electrical systems that demand reliable performance day after day. Built as a time-delay, current-limiting cartridge fuse, the TR9R is designed to handle temporary startup surges without unnecessary interruptions, making it especially useful for motor loads, HVAC systems, industrial machinery, and control panels. When equipment powers up, inrush current spikes are common — and this fuse is engineered to handle those moments while still delivering fast protection when real fault conditions occur.

With a 200 kA interrupting rating at 250V AC, the TR9R helps defend valuable electrical equipment against damaging short circuits and overloads before they can escalate into costly downtime or repairs. Its compact cartridge-style body makes it easy to install in a wide variety of commercial and industrial electrical applications where space is limited. Whether you're maintaining an existing system or upgrading protection components, this Class R fuse delivers dependable performance in demanding environments.
