Surge suppression fuse
ETI
SRF Series Surge Fuse
Through the past few years, the transient voltage surge suppresion (TVSS) industry has grown to one of the fastest-growing segments among power protection products. Newness from ETI is series of fuses named SRF (Surge Rated Fuses), intended for the protection of TVSS products. The SRF Series has been designed to survive 8/20 μs lighting surge pulses without operating, allowing the TVSS system to react to the surge. All surge fuses have 8/20 μs ratings, not a continuous current rating. These fuses are intended to be installed in series with the TVSS devices and do not normally carry current, except for the periodic random surges caused by TVSS breakdown during normal operation. Under AC short circuit conditions these SRF surge suppression fuses have extremely high capability for current limitation.
