The Mitsubishi FR-A840-0.75K-1 sits in the FR-A840 family of three-phase 400 V inverters and is specified for a 0.75 kW motor — output capacity 1.9 kVA, output rated current 2.5 A, output voltage class three-phase 380–500 V. It is a low-end frame in the series rather than a derated derivative, so a panel that needs to drive a 0.75 kW induction machine should land on this code rather than a larger FR-A840 and de-rate.
Electrical fit for the BOM line
On-board communications are RS-232 / RS-422 / RS-485 only — no Profinet, EtherCAT or Ethernet/IP port is declared on this listing, so any fieldbus uplink needs an option card or an external gateway that sits in front of the serial port.
The unit is listed with CE / UL / cUL representative standards and RoHS compliance level 6 — that is the compliance set shown for this line; REACH and IEC declarations are not in the listing and would need to be pulled from the manufacturer's declaration pack at the time of order.
Putting it on the BOM
For a green-field panel this code can be specified directly: 400 V three-phase in, 0.75 kW three-phase out, RS-232/422/485 for serial comms, CE/UL/cUL and RoHS 6 compliance — those are the constraints a controls integrator has to honour. Anything beyond — Profinet, Ethernet/IP, a safety function, a brake transistor for vertical loads — is an option card or an external module, not a feature of the base unit as listed.
