22 kW, 44 A constant-torque drive for moderate-to-heavy loads
The FR-A840-00620-2-60 is a 22 kW rated AC drive from Mitsubishi Electric's FR-800 series, delivering 44 A output current in constant-torque duty class — meaning it handles both moderate and heavy load profiles without derating the torque-speed curve. Input is three-phase 400/415 VAC; the IP20 enclosure suits cabinet-mount installations where the drive is protected from dust and moisture ingress by the panel itself.
Constant-torque duty class and what it means for motor matching
The constant-torque rating (moderate and heavy duty) means the drive delivers full rated torque from zero to base speed without current foldback — essential for conveyors, extruders, mixers, and positive-displacement pumps that demand rated torque across the speed range. The 44 A output matches a 22 kW four-pole induction motor at 400 V in constant-torque service; for variable-torque loads (centrifugal pumps, fans) the same drive can typically drive a larger motor frame, but the constant-torque current ceiling governs the thermal limit.
Active lifecycle — current production status
For a critical-spare holding strategy, buy one for the cabinet before the first failure — the FR-800 series is widely installed, and a spare on the shelf keeps a line down to a swap-out window rather than a procurement lead time.
Sourcing and availability — quoted to order
Sourced through independent distribution channels; availability and current pricing confirmed at RFQ against the BOM quantity. The estimated lead time window is 1–10 working days from order confirmation, subject to distributor stock position at time of quote.
