The Delta VFD17AMH43ANSAA is a 7.5 kW (10 HP) frequency converter in Frame D, sized for a 3-phase 380–480 VAC induction motor. Its Heavy Duty rating of 19.3 A covers constant-torque loads like conveyors and positive-displacement pumps; the Normal Duty rating of 21.8 A suits variable-torque fans and centrifugal pumps where the drive can ride the square-law curve. The drive is naturally cooled (no fan), which eliminates a common failure point in dusty environments but means the enclosure must allow free convection airflow — don't box it in a sealed sub-panel without a thermal calculation. IP20 limits it to a clean, dry cabinet; this is a panel-mount drive, not a standalone unit.
Frame D footprint and panel integration
Frame D is the mechanical envelope for this power class. The VFD17AMH43ANSAA shares the same frame as the lower-rated VFD13AMH43ANSAA (5.5 kW) — same bolt pattern, same gland-plate area, same DIN-rail or backplate mounting. If a panel was laid out for the 5.5 kW sibling, this drive drops in without re-drilling or re-routing the power wiring. The EMC filter is optional on this variant (suffix 'A' in the order code). If the installation must meet conducted-emission limits for the environment — residential or light-industrial second environment — an external filter or a different variant with the filter built in will be needed. Plan the gland plate space accordingly.
