Note 1. The resistor plus capacitor measurement provides a guide to the leakage current level that
Note 2. The clamp leak tester measurement is the leakage current actually detected at the inverter
Actual Selection
 The leakage breaker starts to detect leakage current from 50% of the rated leakage current, so
provide a margin of two times.
 Also, a large amount of leakage current will flow from the noise filter. Leakage current form other
Controllers should also be added to the total leakage current.
 To prevent incorrect operation due to inrush current, it is necessary to select a current value of ten
times the total leakage current for uses other than surge resistance.
 Refer to the specifications from the relevant manufacturer for information on leakage breakers.
