Circuit breaker failure protection CCBRBRF1_50BF-1 is initiated via the PICKUP input
by number of different protection functions available in the relay. The breaker failure
protection function offers different operating modes associated with the circuit breaker
position and the measured phase and residual currents.
The circuit breaker failure protection function has two operating outputs: TRRET and
TRBU. The TRRET trip output is used for retripping its own breaker through
TRPPTRC2_86/94-2_TRIP. The TRBU output is used to give a backup trip to the breaker
feeding upstream. For this purpose, the TRBU trip output signal is connected to the binary
output X100:PO2.

Figure 64: Circuit breaker failure protection function
Three arc protection stages ARCSARC-1…3_AFD-1...3 are included as an optional
function. The arc protection offers individual function blocks for three arc sensors that can
be connected to the relay. Each arc protection function block has two different operation
modes, that is, with or without the phase and residual current check.
The trip signals from ARCSARC-1…3_AFD-1...3 are connected to both trip logic
TRPPTRC1_86/94-1 and TRPPTRC2_86/94-2.
