RF119

  • Retrofit non directional overcurrent protection adapter for 7SG1114 and  KCGG140 relays
  • Numerical multifunction relay
  • Easy changeover from old to new




The RF119 is a retrofit adapter relay housing a 7SR1103 (four pole non directional overcurrent protection relay) developed as a change out relay insert for either the 7SG1114 Argus or KCGG140 relays.

There are 4 variations of the RF119, to suit the 7SG1114 Reymos Case, the KCGG140 Midos case and two wiring variants to suit the 7SG1114 Epsilon case.

The adapter allows a quick upgrade to the latest generation of hardware technology, without the need for installing a new case or wiring in a substation.
