9.3.2 Contact voltage

Measuring range according to EN61557-6 is 3.0 V ÷ 49.0 V for limit contact voltage 25
V.
Measuring range according to EN61557-6 is 3.0 V ÷ 99.0 V for limit contact voltage 50
V.
Measuring range (V)
0.0 ÷ 9.9
10.0 ÷ 99.9
Accuracy applies for 1 year in reference conditions. Temperature coefficient outside
these limits is +1 digit.
Test current ...................................... max. 0.5 × I
Limit contact voltage ......................... 25 V, 50 V
Fault loop resistance at contact voltage is calculated as

9.3.3 Trip-out time

Complete measurement range corresponds to EN61557-6 requirements. Specified
accuracies are valid for complete operating range.
