Overview

The Mersen Amp-Trap® R-Rated DIN style fuse (SKU: A072D1DSR0-6R) provides essential short-circuit protection for medium voltage motors and motor controllers. Designed to meet North American R-Rated performance standards within an IEC 282-1 DIN mounting configuration (442mm), this fuse is a critical component for combination motor starters. It functions as a back-up fuse, featuring a minimum interrupting rating and requiring coordination with overload relays. The R-Rated designation signifies that the fuse will melt within 15 to 35 seconds at 100 times its 'R' rating, as per ANSI C37.46-2000. This specific model operates at 7.2 kV and has a continuous amp rating of 6R at 40°C, with a minimum interrupting rating of 50kA RMS at 7.2kV. It includes a visual indicator for positive identification of an open fuse. All fuses in this product group are UL component recognized. The fuse holder is SI 24/442 (Ref # K209424) and it complies with IEC 282-1 and DIN standard 43625. Note that ratings above 19R can be achieved by paralleling fuses; consult the factory for details. This fuse is manufactured in the US.
