Mersen Tri-Onic® TRS-R Power Fuses

Mersen Tri-Onic® TRS-R Power Fuses are current-limiting, time-delay fuses engineered for motor and transformer overcurrent protection. These fuses feature proven time-delay characteristics that safely handle harmless starting currents and inrush currents found in motors and transformers. The rejection-style design prevents replacement errors, and the easy-to-read label offers quick brand recognition and replacement. Dimensional stability is provided even in harsh industrial settings due to the fiberglass body, and the high-grade silica filler ensures fast arc quenching and high current limitation. Mersen Tri-Onic TRS-R Power Fuses are ideal for service entrance equipment, branch circuits, general-purpose equipment, and motor circuits.
