Note:A box (■) in the above table replaces S (Basic type) or E (EMC filter built-in type) depending on the enclosure.
A box () in the above table replaces GA, GB or C depending on the model.
• 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 RCD/ELCBs to be used in the power control panel with an
internal temperature of lower than 50°C (122°F). The rated current is factored by a correction coefficient of 0.85
as the RCDs’/MCCBs’ and ELCBs’ original rated current is specified when using them in a surrounding
temperature of 40°C (104°F) 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 HIV (allowable surrounding temperature: 75°C (167°F))
wires 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 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.
