TR80R - 80 Amp Fuse

TR80R - 80 Amp Fuse

When electrical equipment starts up, it often pulls a temporary surge of power. That’s normal—but without the right protection, those surges can cause nuisance fuse blowouts and unnecessary downtime. The TR80R Class R Time-Delay Fuse is built to handle those everyday demands while helping protect your system from damaging overloads and short circuits. Rated for 80 amps with a 200 kA interrupting capacity at 250VAC, the TR80R is a solid fit for commercial and industrial electrical systems where dependable performance matters. Its time-delay design allows motors, transformers, HVAC equipment, and similar applications to start normally without interrupting operation. At the same time, the fuse responds quickly during fault conditions to help protect connected equipment from costly electrical damage. The knife-blade style construction offers a secure connection in compatible fuse holders and disconnects, making installation straightforward for electricians and maintenance teams alike. Its compact footprint also helps when working in tighter panels or crowded electrical enclosures. Whether it’s being used in a motor circuit, distribution panel, or industrial control setup, the TR80R delivers the kind of reliable protection that helps keep equipment running and downtime to a minimum.
