Overview

The Mersen A055B1DAR0-10E is a Medium Voltage E-Rated Fuse, engineered for the critical protection of transformers and distribution lines. This current-limiting fuse offers essential overload and short circuit protection, designed to operate at currents as low as 1.7 times its rated current, up to its maximum interrupting rating. Its design specifically accounts for transformer magnetizing inrush current, making it a vital component for maintaining system integrity. The A055B1DAR0-10E features a single barrel construction with a 3-inch diameter (size D) and bolt-on end mounts, facilitating direct attachment to equipment bus or terminal pads. A visual indicator is integrated to provide clear operational status. Manufactured in the USA by Mersen, this fuse adheres to the UNSPSC code 39121626. Its robust construction and precise current-limiting capabilities ensure reliable protection for sensitive electrical equipment, contributing to minimized downtime and the prevention of potential damage. Key specifications include a voltage rating of 5500 VAC and a current rating of 10 A, with a size D (3-inch diameter) and bolt-on connection type.
