The circuit breaker failure protection function has two operating outputs:
TRRET
and
TRBU
. The
TRRET
operating output is used for retripping its own breaker through
TRPPTRC2_TRIP. The output
TRBU
gives a backup trip to the breaker feeding
upstream. For this purpose, the
TRBU
operating output signal is connected to the
binary output X100:PO2.

Figure 21:
Circuit breaker failure protection function
Three arc protection ARCSARC1...3 stages 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 operating signals from ARCSARC1...3 are connected to both trip logic
TRPPTRC1 and TRPPTRC2. If the relay has been ordered with high speed binary
outputs, the individual operating signals from ARCSARC1...3 are connected to
dedicated trip logic TRPPTRC3...5. The outputs of TRPPTRC3...5 are available at
high speed outputs X110:HSO1, X110:HSO2 and X110:HSO3 respectively.
