GUID-65E0C573-F286-41A8-93CB-CB24321A0004 V1 ENFigure 40: Circuit breaker failure protectionThe circuit-breaker failure protection (CCBRBRF1) is initiated via the start inputby a number of different protection stages in the IED. CCBRBRF1 offers differentoperating modes associated with the circuit-breaker position and the measuredphase and residual currents.CCBRBRF1 has two operating outputs: TRRET and TRBU. The TRRET operateoutput is used for retripping its own circuit breaker through the Master Trip Logic2. The TRBU output is used to give a backup trip to the circuit breaker feedingupstream. For this purpose, the TRBU operate output signal is connected to theoutput PO2 (X100: 8-9). LED 7 is used for backup (TRBU) operate indication.3.6.3.2 Functional diagrams for disturbance recorder and supervisionfunctions1MRS756498 D Section 3RED615 standard configurationsRED615 65Application Manual
