SFT & SF2T Time Lag Acting Thin Film Chip Fuses

Vishay / Sfernice SFT and SF2T Time Lag Acting Thin Film Chip Fuses endure temporary, non-damaging spikes while providing reliable overcurrent protection. Vishay / Sfernice SFT and SF2T time lag acting fuses are ideal for motors, transformers, and other equipment that generate inrush currents during startup. SFT time lag acting fuses are designed to open in t = <5s at 250% overload, while SF2T long time lag acting fuses are set to open within t = 1s to 120s at 200% overload.
