- Install the MCCB or RCD/ELCB at the input side of the inverter. They cannot be installed at the
output side of the inverter.
- The above table lists the rated current of MCCBs and RCDs/ELCBs to be used in the power control
panel with an internal temperature of lower than 50
°
C. The rated current is factored by a correction
coefficient of 0.85 as the MCCBs' and RCD's/ELCBs' original rated current is specified when using
them in an ambient temperature of 50
°
C or lower. Select an MCCB and/or RCD/ELCB suitable for
the actual short-circuit breaking capacity needed for your power systems.
- For the selection of the MC type, it is assumed that the 600 V HIV wires (allowable ambient
temperature: 75
°
C) for the power input/output of the inverter are used. If an MC type for another
class of wires is selected, the wire size suitable for the terminal size of both the inverter and the MC
type should be taken into account.
- Use RCDs/ELCBs with overcurrent protection.
- To protect your power systems from secondary accidents caused by the broken inverter, use an
MCCB and/or RCD/ELCB with the rated current listed in the above table. Do not use an MCCB or
RCD/ELCB with a rating higher than that listed.
