Overview

Mersen M084421 miniature fuse (SKU: M084421) is a 6.3x32mm, 250V, 0.315A medium time-lag (SA) fuse designed for sensitive electronic protection. The SA time-lag characteristic allows brief inrush currents while interrupting sustained overcurrent conditions, making it ideal for semiconductor devices and control circuits. The fuse is rated for 250V AC/DC operation with a breaking capacity suitable for inrush-heavy applications. Clip mounting ensures secure installation in compact housings, and some variants include a trip indicator for visual status confirmation. The 0.315A rating provides precise protection for low-current control circuits, sensors, and communication interfaces. Mersen’s construction uses high-quality materials to ensure consistent performance across temperature variations and electrical stress. The fuse is suitable for industrial automation, power supplies, and instrumentation where reliable overcurrent protection is critical. Order M084421 for dependable protection of sensitive electronics in 125V–250V systems with medium time-lag requirements.
