What sits in the panel
The Delta VFD015E23A is a variable-frequency drive sized for a 2 HP (1.5 kW) motor on a 230 V three-phase mains supply, with the model code itself spelling that out — the 015 segment marks the 1.5 kW rating and the 23 segment marks the three-phase 230 V class. It is the standard-drive variant of the VFD-E family, not a high-performance or application-specific build, which is what the A suffix in the order code is intended to flag for the panel builder reading the nameplate.
Sizing it against the motor it has to run
At 1.5 kW this is the right slot for small three-phase loads — fans, blowers, small pumps, conveyors, mixers — where the drive's three-phase 230 V input matches the motor winding and there is no need for a step-up transformer ahead of it. The form factor is shared with the wider VFD-E line, which means existing panel cutouts, gland plate entries and DIN-rail / panel-mount layouts built for this chassis do not have to be re-engineered when a unit is swapped out, provided the rating is held at or below the original spec.
When the cabinet was built around the 3.7 kW sibling
That shared footprint means VFD015E23A will physically drop into a slot originally specified for the 3.7 kW unit, but the motor output capability drops from 5 HP to 2 HP — the wiring and breaker upstream are not the constraint, the motor's torque demand is, so a substitution has to be confirmed against the driven load before the BOM line is closed.
Sourcing posture for this code
Lifecycle status is recorded as current on the manufacturer's product record, with no official successor or cross-reference flagged in the order-code breakdown — the standard version is still the active build being shipped against new orders.
