FujiAF-300 Mini VFD Inverter Drive, 1 HP, 460 VAC 3-Phase, NEMA 1, No Keypad Fitted

Product Description

What this part is

This is one AF-300 Mini variable frequency drive — a compact V/Hz inverter that takes 460 VAC three-phase line power and produces a variable-frequency, variable-voltage output to run a standard three-phase AC induction motor at adjustable speed. Built by Fuji Electric and sold in North America under the GE AF-300 catalogue, it is a complete wall- or panel-mounted drive, not a control card and not a soft starter. Speed is varied continuously.

Decoding the order code

The catalogue number reads field by field. 6K is the GE/Fuji inverter product code. M$ is the drive family, AF-300 Mini; sister families in the same scheme are E$ (AF-300 E), G11 and P11, which are not interchangeable with a Mini. 2 is the series revision, the second product revision of the family. 43 is the input rating: 460 VAC, 50/60 Hz, three phase. 001 is the horsepower rating: 1 HP. N is the factory-installed option field, None, meaning this unit was built without the keypad option. 1 is the enclosure code: NEMA 1 / UL Type 1, indoor general purpose. A1 is the product revision and minor revision, first and first.

A number that is not a horsepower rating

The 300 in AF-300 is the drive family designation, not a rating. This is a 1 HP drive. The horsepower is carried in the 001 field of the catalogue number.

What these specs mean in practice

A 1 HP 460 V frame suits small pump, fan, conveyor and mixer loads, where a drive is fitted for soft starting and turndown. The NEMA 1 enclosure is rated for a clean, dry, reasonably cool cabinet or wall location, and is not rated for washdown, coolant mist or metal dust. With the option field set to N, speed reference and start/stop come from the terminal strip — an analog reference and dry contacts, or a serial link if fitted — unless a keypad or remote operator panel is added. Sink or source polarity on the digital inputs is set by the drive’s wiring and configuration.

Published specifications

Motor rating: 1 HP. Input: 460 VAC, three phase, 50/60 Hz. Output: three-phase variable frequency and variable voltage for an AC induction motor. Enclosure: NEMA 1 (UL Type 1), indoor. Factory keypad option: not fitted (N). Family: AF-300 Mini, second series revision.

Quantity and configuration

No keypad or remote operator panel, no motor, no line reactor or load reactor, no dynamic-braking resistor, no EMC filter, no dust cover, no mounting hardware and no manual are included. The N in the catalogue number is the reason the keypad is absent: that is how the unit was built.

Interchange guidance

Searched as 6KM$243001N1A1, 6KM243001N1A1, 6KM 243001 N1A1, 6KMS243001N1A1, AF-300 Mini, AF300 Mini and GE AF-300 1HP 460V. The $ in the family field is a literal character in the GE/Fuji catalogue scheme, and it is frequently transcribed as an S or dropped entirely. 6KM$243001X1A1 is the same drive supplied with the keypad option. 6KM$143001N1A1 is the first-series-revision drive, the same 1 HP 460 V frame differing only in the revision field, so both are listed as cross-references. The AF-300 line is Fuji Electric hardware sold under GE, later GE Industrial Systems, and the AF-300 range is succeeded by Fuji’s FRENIC family.
