According to the result of calculation, use a leakage current breaker having the rated sensitivity current (Ig)
of 4.0[mA] or more. A leakage current breaker having Ig of 15[mA] is used with the NV-SP/SW/CP/CW/HW
series.

Note 1. For 1-phase 200V to 230VAC power supply, connect the power supply to L1,L2 and leave L3 open.
There is no L
