What this drive does in the panel
The VFD4A2MH43ANSAA: It is rated to drive a 1.5 kW / 2 HP motor, with a rated output of 4.6 A and 3.5 KVA — meaning the sizing decision is the 1.5 kW shaft load, not the headline input figure; overspec the motor nameplate and the drive will current-limit before it delivers full torque.
Heavy-duty vs normal-duty current
The nameplate carries two duty ratings: Heavy Duty at 5.8 A input / 4.6 A output and Normal Duty at 6.4 A input. Heavy Duty is the conservative figure used for constant-torque loads (conveyors, mixers, extruders) where the drive must deliver 150 % overload for short windows; Normal Duty targets quadratic-torque loads (fans, centrifugal pumps) where thermal headroom matters more than peak torque. Carrier frequency is adjustable from 2~15 kHz with a 4 kHz factory default, so the audible motor whine can be tuned down for noise-sensitive installations — at the cost of additional switching losses and derated continuous output current, which the duty figures already account for at the default setting.
Mechanical fit and panel-side handling
Frame B with natural convection cooling and an IP20 rating puts this drive on a flat panel surface inside an enclosure — it is not sealed against washdown or dust ingress, so the cabinet itself provides the environmental barrier in any food-grade or outdoor deployment. The optional EMC filter on this variant means conducted emissions filtering is not built in by default; installations near sensitive instrumentation or sites bound by EN 61800-3 Category C2/C3 will need an external line filter specified separately rather than assumed in the BOM.
Cross-reference against the smaller-frame sibling
The closest functional sibling in the same 480 V line is VFD3A0MH43ANSAA at Frame A with a 0.75 kW / 1 HP rating and 3.3 A output — it shares the 323~528 Vac input range and the 2~15 kHz carrier, so an existing panel wired for the smaller drive cannot accept this unit without verifying terminal pitch and DIN footprint, because the frame size and connector geometry differ even when the control terminals match.
Sourcing posture for this code
For panel builders stocking MRO spares, the 3-phase 480V drive family offers a clean ladder across 0.75 kW / 1.5 kW / 3.7 kW at the same frame architecture — consolidating the SKU set on this voltage class reduces the bin count versus mixing 230 V and 480 V variants on the same shelf.
