DEIF RMC-142D Current relay

RMC-142D

Current relay

DEIF’s RMC-142D stator earth fault relay protects genset operators against electric shock in case of earth faults in the generator’s stator.

DEIF’s RMC-142D stator earth fault relay protects genset operators against electric shock in case of earth faults in the generator’s stator.

The relay also protects against loss of excitation in case of earth fault in the stator.

The RMC-142D is part of DEIF’s complete range of relays for protection and control of generators featuring a number of adjustable parameters.
