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. Optional solid-state SmartSpot indicator. Rejection-style design prevents replacement errors (when used with recommended fuse block). Application Motor Circuits, Mains, Feeders, Branch Circuits, Transformers, Service Entrance Equipment, General-Purpose Equipment. Mersen (also known as Ferraz Shawmut and Gould Fuses).
