Mersen TR2-1/2R Fuse TR-R Class RK5 Time-Delay 250VAC/VDC 2.5A Ferrule

Product Description

The Mersen TR2-1/2R is a Class RK5, TR-R series, current limiting time delay fuse engineered for overcurrent protection. This 2.5A, 250VAC/VDC fuse is suitable for motors, transformers, service entrance equipment, feeders, and branch circuits. Its time-delay characteristics handle 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 TR2-1/2R fuse provides reliable overcurrent protection with time-delay functionality and a rejection-style design.
