connected to U3PBB1 on SESRSYN for WA2_QA1. The voltage from the line VT is connected to
U3PLN1 on both function blocks. The condition of VT fuses shall also be connected as shown in
. The voltage selection parameter
CBConfig is set to No voltage sel. for both function
blocks.

1 1/2 circuit breaker
M12330-3 v8
Figure
describes a 1 ½ breaker arrangement with three SESRSYN functions in the same
IED, each of them handling voltage selection for WA1_QA1, TIE_QA1 and WA2_QA1 breakers
respectively. The voltage from busbar 1 VT is connected to U3PBB1 on all three function blocks
and the voltage from busbar 2 VT is connected to U3PBB2 on all three function blocks. The
voltage from line1 VT is connected to U3PLN1 on all three function blocks and the voltage from
line2 VT is connected to U3PLN2 on all three function blocks. The positions of the
disconnectors and VT fuses shall be connected as shown in Figure
