Overview

The Mersen ATQR2/10 is a Class CC time-delay fuse designed for superior protection of branch circuits. Engineered with a rejection-style design, it prevents improper fuse replacement when used with recommended fuse blocks, ensuring system integrity. This 0.2A fuse operates at 600VAC and 300VDC, with a high interrupting rating of 200kA AC and 100kA DC, providing robust protection against high fault currents. Its time-delay characteristic is specifically suited for inductive loads, effectively handling the high inrush currents of control transformers and solenoids without nuisance tripping. The ATQR2/10 features a fiberglass body for dimensional stability in industrial settings and a high-grade silica filler for fast arc quenching and current limitation. A high-visibility orange label aids in quick identification and replacement, while metal-embossed date and catalog numbers ensure traceability. This fuse is UL listed to standard 248-4 and CSA certified to standard C22.2 No. 248.4, making it a reliable choice for critical applications. SKU: ATQR2/10. Manufacturer: Mersen. UNSPSC Code: 39121604.
