Ferraz Shawmut TR-R Series Polyester 250 Vac/Vdc Current Limiting Dual Element Time Delay Fuse

With advanced material technology added to the existing product, the Tri-Onic® TR current-limiting time-delay fuses are engineered for overcurrent protection of motors and transformers, service entrance equipment, feeder and branch circuits. TriOnic fuse's proven time-delay characteristic safely handles harmless starting currents and inrush currents associated with today's motors and transformers. Now available with optional SmartSpot® blown fuse indication technology.
