ATQR8 Description

Short technical summary and product information.

The Mersen ATQR8, part of the AMP-TRAP 2000® family, is a Class CC time delay fuse engineered to protect branch circuits in electrical distribution systems. Its time delay characteristics are specifically suited for high inrush currents common in control transformers, solenoids, and similar inductive loads, preventing nuisance openings.

 

This fuse features a high current limiting capability, ensuring low peak let-thru current. The rejection-style design prevents improper fuse replacement when used with recommended fuse blocks. Its fiberglass body provides dimensional stability in demanding industrial environments, while the high-grade silica filler facilitates fast arc quenching.

 

Key specifications include a voltage rating of 600VAC with a 200kA interrupting rating and 300VDC with a 100kA interrupting rating. The ATQR series is UL Listed to Standard 248-4 and CSA Certified to Standard C22.2 No. 248.4.

 

Applications for the ATQR8 include protection for control transformers, solenoids, inductive loads, and general-purpose lighting and heating circuits. Its high-visibility orange label aids in quick identification and replacement.
