TR-R Tri-Onic® Power Fuses

Mersen TR-R Tri-Onic® Power Fuses provide current limiting for low peak let-thru current and time-delay characteristics. These fuses are designed for the overcurrent protection of motors and transformers, feeders, service entrance equipment, and branch circuits. The proven time-delay features safely handle harmless starting currents and inrush currents found in motors and transformers. The TR-R series is available with optional SmartSpot® blown fuse indication technology. Mersen TR-R Tri-Onic Power Fuses have a fiberglass body for dimensional stability in harsh industrial settings and a high-grade silica filler that ensures fast arc quenching and high current limitation.
