(Note) English characters are included in inverter type ?. S (basic type), E (EMC filter built-in type), H (built-in DC reactor type).
• Install MCCB and ELCB on inverter input side. It can not be installed on the inverter output side.
• For MCCB and ELCB, the recommended rated current value (MCCB, ELCB ground environment condition is selected considering ambient temperature condition correction factor (0.85)) under the condition of 50 ° C or less in board temperature. The specific format should be in accordance with the short circuit breaking capacity of the equipment.
• When selecting the MC, the type of wire to be connected is assumed to be HIV wire (75 ° C tolerance). When selecting with other wires, it is necessary to reselect it taking account of the terminal block size and wire size.
• For ELCB, it has overcurrent protection function.
• Use MCCB and ELCB rated current shown in the above table for prevention of secondary disasters when inverter breakage occurs. Please do not use MCCB, ELCB with rated current larger than necessary.
