Question:
7 s" J# I7 p: P0 ?3 I9.12.13.1 refers to the test conditions prescribed in 9.12.1 and states that the impedance Z1 shall
not be used.
9.12.1 refers to the conditions in 9.12.1 to 9.12.12.
% W# K. E7 \5 P8 B2 E9.12.2 and 9.12.7.4 require the test circuits according to figures 5 to 9 together with impedance
Z2 to be used.
According to these figures the following inconsistency appears:
For a single pole switch (with two current paths) normally rated for 230 V, the rated residual

: D8 [9 p9 }9 ?For a two pole switch normally rated for 400 V, the rated residual making and breaking
capacity has to be tested at 400 V.
For a three pole switch normally rated for 400 V, the rated residual making and breaking
capacity has to be tested at 400 V.
For a three pole switch with four current paths and for a four pole switch normally rated for
8 X9 w% T4 }- l( T. o* D400 V, the rated residual making and breaking capacity has to be tested at 230 V.
Due to the fact that the purpose of this test is not to cover the special fault conditions in IT-systems,
2 e/ d9 c: N% hthe test voltage for this verification of the rated residual making and breaking capacity should be
230 V, independent of the number of poles, and the relevant figures should be corrected.
