Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
Where it sits in the control system
The VFD002EL21A is the device-level element in a Delta variable-frequency drive installation. It receives the field signals and control supply listed above — 1-phase 200...240 V / 3-phase 380...480 V AC — and switches or conditions the load within the 3-phase 400 V AC ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in pump sets, conveyor belts, fan and compressor drives, where the unit is matched to the original catalog number and the enclosure provides Cabinet / DIN rail support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
