available. This configuration is available for only three REB670 variants (that is A31, B21and B31). It shall be noted that optional functions breaker failure protection CCRBRF(50BF), end fault protection and overcurrent protection PH4SPTOC (51) can be orderedtogether with this configuration, but they will not be pre-configured. Thus these optionalfunctions shall be configured by the end user.3.1.4 Configuration X03This configuration includes BBP with breaker failure protection CCRBRF (50BF), endfault protection and overcurrent protection PH4SPTOC (51) for double busbar-singlebreaker stations, where Zone Selection is done by using a and b auxiliary contacts fromevery disconnectors and/or circuit breakers. Thus full disconnector/breaker supervision isavailable. This configuration is available for only three REB670 variants (that is A31, B21and B31).In order to use X03 configuration, optional breaker failure and overcurrent functions mustbe ordered.3.1.5 Description of 3 ph package A20AThree-phase version of the IED with two low-impedance differential protection zones andfour three-phase CT inputs A20A.
