Note 1� Leakage current varies depending on the capacity of the motor to be connected,
cable length and surrounding environment. Therefore, when protective measures
from the leakage are taken, measure the leakage current at the locations where the
leakage breaker is installed.
Regarding the leakage breaker, it is necessary to have a clear purpose for
selection such as a fire protection or protection of human body.
Use the harmonic type (for inverter) for a leakage breaker.
