Technical data of measuring devicesWhen the REC 523 device is configured, the technical data of the measuring devicesis set in separate dialogue boxes in the Relay Configuration Tool. The set valuesaffect the measurements carried out by the REC 523 device.Values to be set for a current transformer:ï Rated primary current (1...6000 A)1 of the primary current transformerï Rated secondary current (5 A, 2 A, 1 A, 0.2 A) of the primary current transformerREC523F 034AAA (wall-mounted)REC523F 039AAA (flush-mounted)4 current transformers 1/5 A3 voltage transformers 230 VUaux = 80-265 V AC/DCREC523F 034CAA (wall-mounted)REC523F 039CAA (flush-mounted)4 current transformers 1/5 A3 voltage transformers 230 VUaux = 18-80 V DCREC523F 054AAA (wall-mounted)REC523F 059AAA (flush-mounted)1 current transformer 0.2/1 A4 current transformers 1/5 A4 voltage transformers 100 VUaux = 80-265 V AC/DCREC523F 054CAA (wall-mounted)REC523F 059CAA (flush-mounted1 current transformer 0.2/1 A4 current transformers 1/5 A4 voltage transformers 100 VUaux = 18-80 V DCREC523F 060AAC (wall-mounted)REC523F 065AAC (flush-mounted)9 sensor channels(current sensor or voltage divider)Uaux = 80-265 V AC/DCREC523F 060CAC (wall-mounted)REC523F 065CAC (flush-mounted)9 sensor channels(current sensor or voltage divider)Uaux = 18-80 V DCREC523F 061AAA (wall-mounted)REC523F 066AAA (flush-mounted)6 current transformers 1/5 A3 voltage transformers 100 VUaux = 80-265 V AC/DCREC523F 061CAA (wall-mounted)REC523F 066CAA (flush-mounted)6 current transformers 1/5 A3 voltage transformers 100 VUaux = 18-80 V DCREC523F 062AAA (wall-mounted)REC523F 067AAA (flush-mounted)3 current transformers 1/5 A6 voltage transformers 100 VUaux = 80-265 V AC/DCREC523F 062CAA (wall-mounted)REC523F 067CAA (flush-mounted)3 current transformers 1/5 A6 voltage transformers 100 VUaux = 18-80 V DCTable 5.3.1-1 REC 523 versions and analogue channels (Continued)REC 523 version Analogue channelWhen the values listed below for the measuring devices are changedvia the Relay Setting Tool, the new values take effect only after theyhave been stored and the relay has been reset.1.
