The S1 Cutout consists of a base and a handle that provides a convenient means of testing the field circuit without disconnecting the field cables from the CCR.  The S1 Cutout can be installed internally within the CCR or external to the CCR.

  • Compatible with all types of L-828/L-829 CCRs and L-847 circuit sensors operating at 6.6A or 20A output current.
  • Designed to operate at 5000V and withstand a hi-pot test of 23kW for 1 minute.
  • Designed for operation from -55 oC to +55 oC and in areas of high humidity.
  • Constructed with flame retardant materials  (solepoxy resin and glastic-fiberglass reinforced thermo-set polyester) specifically selected for their insulation properties.
  • Size compatibility for direct replacement of a majority of existing cutouts.
  • Handles are ergonomically designed to make insertion and extraction effortless.
