The 800VAC Protistor® BS88-4 fuse-link provides maximum flexibility in equipment design and ultimate protection for small power conversion equipment. These fast acting gR fuses have been engineered to provide full range protection to eliminate all overloads and semiconductor fault. They are assembled with die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. Each fuse-link is embedded with a trip-indicator.
