Application

• • CH SRF class II: These fuses are intended for installation in series with TVSS devices and do not normally carry current, except for the periodic random surges caused by TVSS breakdown during normal operation.
  • CH SRF 25kA class I: These fuses are intended for installation in series with TVSS devices and do not normally carry current, except for the periodic random surges caused by TVSS breakdown during normal operation.
  • CH SRF class II - DC: Use in typical DC applilcation: PV Photovoltaic, battery supply, rectifier These fuses are intended for installation in series with TVSS devices and do not normally carry current, except for the periodic random surges caused by TVSS breakdown during normal operation.
