Description
Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.
Features
- Engineered with advanced Tri-Onic® time-delay characteristics, the TR45R safely tolerates temporary, harmless inrush currents during heavy equipment start-ups. This targeted delay eliminates expensive "nuisance tripping," keeping your production lines moving while providing precision overcurrent protection if a true fault occurs.
- Featuring an exceptional 200kA AC breaking capacity at 250V, this Class RK5 fuse delivers ultimate current-limiting protection by rapidly quenching high-energy electrical faults. It forces low peak let-thru currents down stream, shielding your sensitive components, switchgear, and downstream branch circuits from catastrophic thermal and magnetic damage.
- Designed with strict Class RK5 dimensions and a rejection-style ferrule construction, this cylindrical fuse physically prevents the dangerous installation of lower-rated or non-current-limiting Class H or K fuses. This fail-safe geometry guarantees your facility's safety margins and code compliance remain completely uncompromised during routine field service.
- Built with a high-grade fiberglass body for absolute dimensional stability and packed with premium silica filler for rapid arc quenching, the TR45R is built for extreme reliability under severe thermal stress. The tin-plated copper ferrule terminals ensure low-resistance connectivity and long-term corrosion resistance inside clip-style fuse holders.
- Rated for dual 250VAC and 250VDC applications at 45 Amps, this versatile power fuse serves as an ideal protective solution across service entrances, feeders, mains, and complex DC control circuits. This cross-system capability simplifies your facility’s electrical parts inventory, drastically reducing the variety of spares maintenance technicians need to keep on hand.
