The circuit-breaker failure protection CCBRBRF_50BF is initiated via the PICKUP input
by a functions connected to the Master Trip 1 and by opening command of the circuit
breaker. CCBRBRF_50BF offers different operating modes associated with the circuit-
breaker position and the measured phase and residual currents.
CCBRBRF_50BF has two operating outputs: TRRET and TRBU. The TRBU output can be
used to give a backup trip to the circuit breaker feeding upstream. In the configuration the
TRBU output signal is connected to the output SO1 (X100: 14, 15, 16).
CCBRBRF1_50BF-1 use the source 1 (bus 1) voltages whereas CCBRBRF2_50BF-2 use
the source 2 (bus 2) voltages.
