Configuration X02

This configuration includes only busbar protection for double busbar-single breaker
stations, where Zone Selection is done by using a and b auxiliary contacts from every
disconnector and/or circuit breaker. Thus full disconnector/breaker supervision is
available. This configuration is available for only three REB670 variants (that is A31,
B21 and B31). It shall be noted that optional functions breaker failure protection
CCRBRF (50BF), end fault protection and overcurrent protection PH4SPTOC (51) can
be ordered together with this configuration, but they will not be pre-configured. Thus
these optional functions shall be configured by the end user.

Configuration X03

This configuration includes BBP with breaker failure protection CCRBRF (50BF), end
fault protection and overcurrent protection PH4SPTOC (51) for double busbar-single
breaker stations, where Zone Selection is done by using a and b auxiliary contacts from
every disconnectors and/or circuit breakers. Thus full disconnector/breaker supervision
is available. This configuration is available for only three REB670 variants (that is
A31, B21 and B31).
In order to use X03 configuration, optional breaker failure and overcurrent functions
must be ordered.
