Overview

Mersen’s R090681 miniature fuse (6.3x32mm) is rated 220V AC with a 0.4A super slow-blow (TT) HA 24 time-lag characteristic, designed for semiconductor and control circuit protection. The HA 24 time-lag allows brief overloads common in startup or transient conditions while interrupting sustained overcurrent to prevent damage to sensitive electronics. Clip mounting (24) ensures secure retention in fuse holders without soldering, reducing installation time and improving reliability. With a low breaking capacity, this fuse is ideal for low-energy circuits where high interrupt ratings are unnecessary, such as control panels, power supplies, and automation systems. Built to Mersen’s quality standards, the fuse body is constructed for mechanical durability and consistent performance across operating temperatures. The 0.4A rating provides precise protection for low-current semiconductor devices, relays, and signal circuits. Order SKU R090681 for reliable overcurrent protection in 220V AC applications requiring super time-lag response.
