Sizing a 1.5 kW drive on 460 V three-phase
The Delta VFD015E43A sits in the VFD-E series at the 1.5 kW (2 HP) frame on 460 V three-phase mains — the frame's motor ceiling is 1.5 kW, so it covers the 2 HP pump, fan, and conveyor loads typically specified at that rating. Natural cooling means no integral fan — the heatsink relies on cabinet airflow, which matters in a sealed panel where the integrator must confirm the enclosure dissipates the drive's standing losses without forcing a derate.
In-family stepping points
The same VFD-E frame on 460 V three-phase is also offered at 0.75 kW (1 HP) — a half-step down for lighter loads without leaving the 460 V three-phase input class or the natural-cooled footprint.
