PowerFlex Drives & Catalog Numbers

Allen-Bradley PowerFlex, current and obsolete, and how to read a PowerFlex catalog number so you order the right drive.

A PowerFlex catalog number isn't a fixed SKU, it's built from codes that spell out the model, voltage, horsepower, and enclosure. Read it correctly and you know exactly what you have. Here's the structure, with a worked example.

Worked example, 25B-D017N104

Segment	Means
25B	PowerFlex 525 family
D	480V, 3-phase input
017	Current code, ~10 HP at 480V
N	No integral filter
104	Enclosure / version, IP20 (open type)

Result: PowerFlex 525, 480V 3-phase, ~10 HP, IP20. Codes vary by family, always confirm against the nameplate or the Rockwell technical data (TD) for the series.

PowerFlex model status

Model	Status	Notes
525 / 523	Current	Compact AC drives

6000	Current	Medium-voltage
40 / 4 / 40P / 400	Obsolete	Replaced by 520-series
70 / 700 / 700S / 700H	Obsolete	Replaced by 750-series

Frequently asked

How do I read a PowerFlex catalog number?

Read it in groups: the family prefix (e.g. 25B = PowerFlex 525), then a voltage code, then a current/HP code, then enclosure and option codes. A PowerFlex number is configurable, so the same model has many valid numbers, confirm against the nameplate or the Rockwell technical data.

Which PowerFlex drives are obsolete?

The 4, 40, 40P, 400, 70, 700, 700S/700H, and the deep-legacy 1336, 1305, and 160 are discontinued or near end-of-life. The 525/523, 753, 755, 755T, and 6000 are current.

Can you supply an obsolete PowerFlex drive?
