The Mitsubishi FR-A740-22K-CHT is a A700 series inverter rated 22 kW, 44 A, on a three-phase 380 to 480V supply — the standard voltage class for European and Asian motor loads in that power band.
Overload rating is 150% for 60 s and 200% for 3 s (inverse-time), with ambient at 50°C. Regenerative braking torque is 20%, continuous duty — adequate for deceleration profiles on fan/pump loads, but not a vertical-load holding brake.
No. The FR-A820-18.5K is a 200-240V drive, while the FR-A740-22K-CHT is 380-480V. They are not electrically compatible without changing the power supply and motor circuit.
Rated current 44 A, applicable motor 22 kW, output capacity 32.8 kVA, with a 150% overload for 60 seconds.
