Overview

Mersen SKU G085451 is a 6.3x32mm miniature fuse featuring a medium time-lag (SA) characteristic, rated for 500V and 4A. This fuse is specifically designed for the protection of circuits and equipment that experience inrush or transient current conditions. Its SA characteristic provides a balance, allowing for short-term surges without nuisance tripping while ensuring prompt interruption of sustained overloads. This makes it suitable for safeguarding sensitive electronic components, semiconductor devices, power supplies, and control circuits. The fuse offers a very high breaking capacity, contributing to system durability and reliability by effectively handling inrush currents. Manufactured by Mersen, this fuse is part of their 6x32mm semiconductor protection fuse series. Technical specifications include a 500V voltage rating, an ampere range of 0.1A-10A for the series, a 6x32mm size per standard, and a package quantity of 50 pieces per box. Each fuse weighs 2.5 grams. The product is UL/CSA Recognized (E76491).
