Littelfuse L70S25 - Semiconductor Fuse 25A 700V (200kA AIC, VFA)

Littelfuse L70S25 is a semiconductor protection fuse designed for safeguarding sensitive electronic components in industrial power applications. This low-voltage fuse features a 700V voltage rating and 25A current rating with very fast-acting (VFA) interruption characteristics to prevent damage from overcurrent conditions. The compact ferrule-connection design provides reliable mounting in fuse holders while maintaining a 200kA interrupting capacity for high-fault scenarios. Constructed to meet industrial protection standards, this semiconductor-class fuse is commonly deployed in variable frequency drives, rectifiers, and other power conversion equipment where rapid circuit interruption is critical for component preservation.
