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.
