Allen-Bradley 25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104 PowerFlex 525 Drives
Three 480 V, three-phase PowerFlex 525 Frame A drive ratings without integral EMC filter.
System Overview
Allen-Bradley 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 are PowerFlex 525 AC drives for 380 to 480 V three-phase input and 0 to 460 V three-phase output. They share the no-integral-EMC-filter N104 suffix and Frame A mechanical classification.
The common drive architecture includes an embedded EtherNet/IP port and integral RS485/DSI communication, while the PowerFlex 525 range also supports optional communication cards and an optional encoder card. These platform facts provide the control and communication context, not a claim that every option card is fitted to each catalog number.
The ratings distinguish the three variants. 25B-D2P3N104 is 0.75 kW / 1 HP with 2.3 A output current; 25B-D4P0N104 is 1.5 kW / 2 HP with 4.0 A; and 25B-D6P0N104 is 2.2 kW / 3 HP with 6.0 A. All three are listed as 323 to 528 V input-range Frame A entries.
Frame A dimensions are 72 by 152 by 172 mm with 57.5 mm and 140 mm reference dimensions in the official drawing, and approximate weight is 1.1 kg. The rating selection must still follow the full model, output current and application duty rather than the shared enclosure frame alone.

Three output-current steps in one frame
Rating comparison
Three output-current steps in one frame
25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 use the same Frame A class, yet their published output currents are 2.3 A, 4.0 A and 6.0 A respectively. The shared frame does not erase the rating step between the models.
Their normal and heavy-duty ratings match within this low-power group: 0.75 kW / 1 HP, 1.5 kW / 2 HP and 2.2 kW / 3 HP in the listed order.
- 2.3 A / 4.0 A / 6.0 A
- 0.75 / 1.5 / 2.2 kW
- All Frame A

Frame A installation envelope
The PowerFlex 525 Frame A reference dimensions are 72 by 152 by 172 mm, with a 1.1 kg approximate weight. The N104 models are the no-integral-filter version in the 380 to 480 V range.
The official PowerFlex figure provides the A-to-E frame geometry and identifies the embedded EtherNet/IP and integral RS485/DSI communications described for PowerFlex 525 drives.

Frequently Asked Questions
Three drives share a Frame A enclosure; how can motor selection still be tied to the correct output-current step (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
The published configuration confirms that 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 are all Frame A, but their output currents are 2.3 A, 4.0 A and 6.0 A respectively.
When a motor nameplate is compared with the order, which kW, HP and amp values distinguish the three catalog numbers (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
For a replacement decision, the listed data shows that 25B-D2P3N104 is 0.75 kW, 25B-D4P0N104 is 1.5 kW and 25B-D6P0N104 is 2.2 kW in the listed 480 V rating table.
A 480 V installation has no external filter decision recorded; what does the N104 suffix establish before wiring starts (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
The installation check is resolved by the fact that 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 are listed for 380 to 480 V three-phase input and 0 to 460 V three-phase output.
A drive is being moved between three-phase cabinets; which published input and output voltage window must remain unchanged (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
In the official technical record, 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 are the no-integral-EMC-filter versions in their listed voltage class.
For a controller that needs both Ethernet and serial-drive context, which built-in PowerFlex 525 communication paths are stated (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
The relevant hardware boundary is that 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 belong to the PowerFlex 525 platform with embedded EtherNet/IP and integral RS485/DSI communications.
A compact cabinet drawing has limited clearance; which Frame A dimensions and weight describe the common mechanical envelope (25B-D2P3N104 / 25B-D4P0N104 / 25B-D6P0N104)?
For engineering selection, the documented result is that 25B-D2P3N104, 25B-D4P0N104 and 25B-D6P0N104 share Frame A reference dimensions of 72 x 152 x 172 mm, while each has a different output-current rating.
