Mitsubishi's FRA76004960NA inverter is designed for three-phase systems, with input voltage specifications ranging from 525 to 600 AC volts. This device is capable of supporting motor capacities as high as 355 kW and carries a rated current of 647 Amps.
It is notable for its overload current capability, allowing 110% for a duration of 60 seconds and 120% for a brief period of 3 seconds, specifically at an air temperature of 40°C. The operating environment should remain within the indoor range, with permissible temperatures extending from -10 °C to +50 °C.
The inverter does not include an integrated fan, relying on a forced air cooling system instead. Furthermore, this unit comes in an open-type enclosure, weighing around 370 kg, which further emphasizes its robust design. Please note that no brake transistor is included, ensuring that the system remains streamlined and focused on inverter functions alone. This model adheres to U.S. specifications, making it suitable for specific applications that require compliance.
