Precautions
Install an ELCB at the No Fuse Breaker (NFB) or manual switch of the branch circuit marketed “
※
” near the packaged
A/C.
Use a high-sensitivity, high-speed (trip time < 0.1 second) ELCB of the required capacity for high frequency operation
(for inverter use).
“B” and “C” in the table below refer to “Method B” and “Method C”.

● ELCB Selection
Determine the rated current of the ELCB based on the total wiring
capacity shown in the right table.
Determine the ELCB model, sensed current, and trip current based
on the information shown in the right table.
*Use high-sensitivity, high-speed (trip time < 0.1 second) ELCB.
*Confirm the ELCB rated current, sensitivity, and trip time and
protective coordination of the upper part.

Note
1.
Use high-sensitivity, high-speed ELCB with rated sensed current under 30mA or medium-sensitivity ELCB with rated
sensed current over 500mA. The trip time of both types must be within 0.1 second.
2. Use high-frequency ELCBs for inverter use.
● Select transformers according to the instructions below.
