The 690/700V SB aR fuse-links are engineered to offer exceptional flexibility in equipment design while ensuring superior protection for modern power conversion systems. These ultra-fast acting square body fuse-links come in various body sizes, each compatible with multiple globally accepted mounting styles.

Designed specifically for safeguarding semiconductor devices such as diodes, thyristors, and IGBT components, the SB aR fuse-links utilize die-cut elements embedded in solidified sand, effectively controlling arcing characteristics. This design results in a lower I²t value and a high interrupting rating level. Furthermore, all contact surfaces are silver-plated, and the hardware is constructed from non-magnetic materials.

Each fuse-link can be equipped with a low voltage trip-indicator, which is capable of activating a field-mountable microswitch, enhancing operational safety and monitoring capabilities.
