Figure 116: Connections of the SESRSYN (25) function block in a double breaker arrangement
A double breaker arrangement requires two function blocks, one for breaker WA1_QA1 and one for
breaker WA2_QA1. No voltage selection is necessary, because the voltage from busbar 1 VT is
connected to V3PB1 on SESRSYN for WA1_QA1 and the voltage from busbar 2 VT is connected
toV3PB1 on SESRSYN for WA2_QA1. The voltage from the line VT is connected to V3PL1 on both
function blocks. The condition of VT fuses shall also be connected as shown in figure 115. The
