TR-R - Class RK5 - Time-Delay
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.
