TR70R - 70 Amp Fuse

TR70R - 70 Amp Fuse

The TR70R Class R Fuse is designed for electrical systems that need dependable protection without constant nuisance trips. Rated at 70 amps, this time-delay fuse helps handle temporary startup surges from motors, transformers, and HVAC equipment while still providing strong short-circuit protection when it matters most. Built with a knife-blade design and current-limiting performance, the TR70R helps protect valuable electrical equipment from damaging fault currents that can interrupt operations and lead to costly repairs. Its 200 kA interrupting rating at 250 VAC makes it a practical choice for demanding commercial and industrial environments where reliability is important day in and day out. Because electrical systems don’t always operate under ideal conditions, a fuse like the TR70R adds another layer of confidence to your setup. Whether installed in a manufacturing facility, distribution panel, control system, or mechanical equipment, this Class R fuse is built to support safer, more consistent electrical performance.
