Mersen TR3-1/2R Fuse 3-1/2A

Product Description

The MERSEN TR3-1/2R is a Tri-Onic TR-R series current limiting time delay fuse designed for overcurrent protection of motors, transformers, service entrance equipment, feeders, and branch circuits. The time delay characteristics safely handle harmless starting currents and inrush currents. It has a cylindrical body made of polyester.

• Time delay for motor start-ups and transformer inrush currents without nuisance opening
• Current limiting for low peak let-thru current
• Rejection style design prevents replacement errors when used with recommended fuse blocks

Product Highlights

This Class RK5 fuse has a voltage rating of 250 VAC/160 VDC and an interrupt rating of 200/20 kA. It features a ferrule terminal and clip mounting.
