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 todays motors and transformers.
