Differential current relays protect the generator against short circuits and leakage currents in the windings of the generator.
Features include
> Measurement of 3-phase currents
> Non-stabilised measurement
> LED indication of fault condition
> Timer-controlled tripping
> LED indication for activated relay
> Extra change-over relay contact for signalling
> 35 mm DIN rail or base-mounting
The protective differential current relay type RMC-131D forms part of a complete DEIF series of relays for protection and control of generators, and is primarily designed for marine applications.
