12. OPTIONS AND AUXILIARY EQUIPMENT
(2) Selection example
Indicated below is an example of selecting a leakage current breaker under the following conditions:
2mm
NV
Ig1
Use a leakage current breaker designed for suppressing harmonics/surges.
Find the terms of Equation (12.2) from the diagram:
5
Ig1 20 0.1 [mA]
1000
5
Ig2 20 0.1 [mA]
1000
Ign 0 (not used)
Iga 0.1 [mA]
Igm 0.1 [mA]
Insert these values in Equation (12.2):
Ig 10 {0.1 0 0.1 3 (0.1 0.1)}
4 [mA]
According to the result of calculation, use a leakage current breaker having the rated sensitivity
current (Ig) of 4[mA] or more. A leakage current breaker having Ig of 15[mA] is used with the NV-
SP/CP/SW/CW/HW series.
