What this 7.5 kW drive handles
The FR-F840-00170-2-60 is a Mitsubishi Electric inverter drive rated for 7.5 kW output at 400 V AC, 3-phase input. It delivers 16 A in Light Duty (LD) mode and 17 A in Super Light Duty (SLD) mode — the SLD rating applies when the load profile stays below 80 % of rated current for extended periods, typical for centrifugal pumps and fans.
Duty ratings and ambient limits
The LD current rating of 16 A is the continuous output at 50 °C ambient; the SLD rating of 17 A applies at 40 °C ambient. This means the drive can deliver more current in cooler environments, but the ambient ceiling drops when you push the output into the higher duty band. For panel builders, the IP20 enclosure means the drive needs clean, dry cabinet space — no washdown or outdoor exposure without an additional enclosure.
