TR8R - 8 Amp Fuse

TR8R - 8 Amp Fuse

The TR8R Class R Fuse is a reliable choice for protecting electrical systems that work hard every day. Rated for 8 Amps and built with time-delay protection, this fuse is designed to handle the temporary power surges that often happen during motor startup or equipment cycling without opening too quickly. That means fewer unnecessary interruptions and better protection for the equipment you depend on. Its current-limiting design also helps reduce the impact of short circuits and overloads, helping protect valuable electrical components from costly damage. With a compact cartridge-style body and a 200 kA interrupting rating at 250 VAC, the TR8R is commonly used in commercial and industrial environments where dependable performance matters. It’s a practical fit for motor controls, HVAC systems, lighting panels, transformers, and other power distribution equipment. The non-indicating design keeps things simple, while the durable Class R construction helps provide consistent overcurrent protection in demanding applications.
