0.4 kW drive on 3-phase 480V — what the rating buys
The Delta VFD004E43A sits in the E Series variable-frequency drive family as the 480V three-phase, 0.4 kW (0.5 HP) step, and is specified for 3-phase 380-480V at 50/60 Hz input with a rated input current of 1.9 A. Output capability is 1.5 A continuous at 1.2 kVA, with the output voltage tracking the input proportionally — so a 380V feed gives a 380V motor, and 480V gives 480V. The drive is rated for motors up to 0.4 kW (0.5 HP), meaning it covers fractional-horsepower loads where you need closed-loop speed control rather than direct-on-line starting. Output frequency spans 0.1 to 600 Hz, which is the speed-control envelope the drive hands the motor — the 600 Hz upper end means the unit can also drive high-speed spindles or small blower applications where the motor nameplate exceeds 50/60 Hz base speed. Sized for fractional-HP pumps, fans, conveyors, and small mixers, it drops into the standard VFD-E footprint and takes its cooling from natural convection rather than a forced-air fan.
Panel fit and form factor
Because output voltage follows input proportionally, the drive does not transform — a 480V panel feeds a 480V motor, and there is no need to overspec the motor insulation for a higher-voltage bus. The commissioning engineer can confirm the motor nameplate voltage matches the supply before first power-up.
Lifecycle and the supply channel
Lifecycle stage is recorded as current, and this is the standard 'A' version of the VFD-E — not a special-build variant — with a typical lead-time window of 1 to 10 working days from the source channel. No official successor or second-source cross-reference is on the record for this exact order code, so the procurement decision rests on the BOM line itself rather than a planned migration.
