Mersen TR17-1/2R Fuse TR Series 250V 17.5A

Product Description

The MERSEN TR17-1/2R is a Tri-Onic TR-R series current limiting time delay fuse engineered for overcurrent protection. This Class RK5 fuse is suitable for motors, transformers, service entrance equipment, feeders, and branch circuits. The time delay safely handles starting and inrush currents.

• 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

The MERSEN TR17-1/2R fuse offers reliable overcurrent protection with time delay functionality and a rejection-style design.
