Earth-leakage current breaker selection example
Selection example
This section shows examples of selecting an earth-leakage current breaker under the following conditions.
MR-J5-_G_ or MR-J5-_A_
Use an earth-leakage current breaker designed for suppressing harmonics/surges.
Find each term of formula (6.1) from the diagram.
Ign = 0 (not used)
Iga = 0.1 [mA]
Igm = 0.1 [mA]
Insert these values in formula (6.1).
Ig
≥
10 • {0.1 + 0 + 0.1 + 1 • (0.1 + 0.1)}
Ig
≥
4 [mA]
According to the result of calculation, use an earth-leakage current breaker having the rated sensitivity current (Ig) of 4.0 mA
or more.
Use an earth-leakage current breaker having Ig of 15 mA for the NV-SP/SW/CP/CW/HW series.
