400 V class drive sized for 4.0 A continuous motor load
Rated for 400 V class input — this Mitsubishi Electric FR-E840-0040-4-60 operates on three-phase 480 V mains, with the ND (normal duty) current set at 4.0 A. That 4.0 A figure is the continuous output current the drive can deliver to the motor without derating; it determines the maximum motor power you can run, typically around 1.5 kW to 2.2 kW depending on the motor efficiency and service factor. The drive ships with a default 50 Hz rated frequency and the monitoring output configured as voltage at terminal AM — standard for 50 Hz regions. If your application runs 60 Hz, you will need to adjust parameter Pr. 3 (base frequency) during commissioning. Safety stop signal is fixed to source logic, meaning the drive expects a 24 VDC source signal to enable the run command. This is the standard safety configuration for Mitsubishi drives and mates directly with most safety relays or PLC safety outputs that source 24 V.
Coated board, no plated conductors — what that means for the panel
The circuit board coating is included — this is a conformal coating that protects against humidity, dust, and mild chemical exposure. It is a meaningful upgrade for panels in washdown areas or unheated enclosures where condensation is a risk. Plated conductors are not present on this variant. That means the main bus bars inside the drive are bare copper rather than tin- or silver-plated. In clean, dry environments this is fine, but if the panel sees corrosive gases (e.g. near a plating line or wastewater treatment), the bare copper may oxidise over time and increase contact resistance. For those environments, consider the -60 variant with plated conductors if available.
Active production, short lead time — sourcing posture
Estimated lead time through distribution is 1 to 10 working days, which indicates healthy stock levels and normal supply chain flow. For production quantities or blanket orders, we can quote against your BOM and confirm firm lead times at RFQ.
