Overview

DEIF’s RMPs are protective overload and reverse power relays and parts of DEIF’s complete range of relays for generator protection and control.

The RMPs are applied for protection of the prime mover against overload and for protection against reverse power.

Protection against overload is crucial in setups where the prime mover is under-dimensioned in proportion to the AC generator.

The versatile units feature a number of adjustable parameters.

RMP Options:

    RMP-111D
    RMP-112D

The protection relays extent to various units listed below. See the DEIF website (www.deif.com) for detailed documentation for each unit.
