Hi, I am Businessman I found this sample from https://www.indomonster.com and think it might be useful to you. ------------------------------------------------------- ABB OVER CURRENT RELAY REJ 521 and REJ 525 REJ 525 is a combined phase and neutral overcurrent relay for short-circuit and time overcurrent protection and non-directional earth-fault protection of overhead lines and cable feeders. REJ 527 is a two-stage directional earthfault relay for the protection of distribution network overhead lines and cable feeders. The relay can also be set for non-directional operation. A special feature of the REJ 527 relay is that its two directional residual overcurrent stages can be set to function as residual overvoltage stages, giving three separate residual overvoltage stages.
