What you're looking at
The FR-A840-00380-2-60 is a Mitsubishi A800 series inverter rated for 15 kW on a three-phase 400/415 V supply. It's a Constant Torque drive, meaning it'll pull its rated torque down to zero speed — that's your machine tool spindle or conveyor drive, where you need muscle at a crawl. Output current is 31 A, which lines up with a standard 15 kW European motor frame. This is the heavy-duty version of that size step — not a light-load fan pump curve. It's for applications that demand full torque throughout the speed range, like extruders or hoists. The IP20 enclosure keeps out finger pokes but not dust or hose-down; it's meant for a clean panel, not a washdown area.
Panel fit and wiring
For wiring, three-phase input connects to R, S, T; output U, V, W to the motor. The drive operates on a three-phase 400/415 V AC supply.
