TR & TRS Series / Class RK5 / Time Delay

The TR & TRS Series / Class RK5 / Time Delay is part of the Mersen (formerly Ferraz Shawmut) general purpose fuses line, distributed by Gross Automation.

TR & TRS Series / Class RK5 / Time Delay

The industry's most popular fuse for motor circuit protection - Tri-Onic® SmartSpot® TR fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line the TR current limiting time delay fuses are engineered for overcurrent protection of motors and transformers, service entrance equipment, feeder and branch circuits. Tri-onic's proven time delay characteristic safely handles harmless starting currents and inrush currents associated with today's motors and transformers.
