Overview

The Mersen D1014579 is a 10x38mm cylindrical fuse engineered for the high-speed protection of semiconductor devices. This gR-class fuse is rated for 16A and 690VAC, providing a rapid response to overcurrents and short circuits. Its design prioritizes the safeguarding of sensitive components commonly found in inverters, Uninterruptible Power Supply (UPS) systems, and variable speed drives. The D1014579 exhibits a low pre-arcing I²t value of 9.3 A²s and a clearing I²t value of 200 A²s, which effectively minimizes the energy let-through during fault conditions. This fuse boasts a rated breaking capacity of 50 kA AC, making it a robust solution for applications where significant fault currents are a concern. Adhering to IEC 269-4 standards, the D1014579 is manufactured in the United States. Its construction features silver-plated ferrules and a ceramic body, contributing to its reliable operational performance. Furthermore, this model holds UL recognition under file E76491. The D1014579 is designed for ferrule mounting. For compatible fuse holders, consult the Mersen catalog, which lists options such as the 9F61AEG201 for internal applications and the 9F61CEF209 for external applications.
