Allen-Bradley 25B-D010N114 PowerFlex 525 4 kW (5 Hp) AC Drive

The filtered 4 kW PowerFlex 525

The Allen-Bradley 25B-D010N114 is the 5 Hp (4 kW) PowerFlex 525 drive with its integral EMC filter. It supplies 10.5 A to the motor from a three-phase 380 to 480V line and is built in frame B.

It is the choice when a mid-size machine needs the 525 feature set and an integrated filter, for example a packaging line with several drives sharing one cabinet.

Technical specifications

Decoding 25B-D010N114

25B is the PowerFlex 525 family, D indicates 480V AC three-phase, 010 equals 10.5 A, and N is the IP20 enclosure. The suffix 114 stands for standard interface, EMC filter fitted and standard braking.

The no-filter match is 25B-D010N104. The two drives have identical ratings, frame and electrical input data, with total losses of 133 W for this one.

Safe Torque Off is certified to ISO 13849-1 SIL 2 and PLd and the drive also carries ATEX, UKCA, RCM and c-UL-us listings as printed in the certification table. Confirm the markings you need in the current document, since approvals can change between revisions.

For replacement work, compare the whole catalog number rather than the horsepower alone. A 5 Hp 480V drive is also offered without a filter, and the physical frame is identical, so the only reliable way to tell them apart before power-up is the emission class digit and the nameplate marking.

Emission and installation considerations

The integral filter reaches Category C2 with 10 m of motor cable and Category C3 with 20 m, from the Rockwell compliance table. External filters can be used for longer runs.

The drive measures 87 x 180 x 172 mm and weighs 1.6 kg. Input is 12.6 kVA at 13.8 A maximum, and UL branch devices are a 30 A fuse, a 100-C23 or 100-E26 contactor and the 140MT-D9E-C16 breaker. IEC fuses run from 20 A to 32 A.

Heat matters at this rating, so add the 133 W of total loss to the cabinet heat load, and do not install the drive where the ambient atmosphere contains volatile or corrosive gas.

Key features of the PowerFlex 525 platform

• Embedded EtherNet/IP port – connects the drive directly to a Logix controller or plant network for control, status and parameter access without an add-on communication card.
• Safe Torque Off built in – removes torque-producing power to the motor through a hardwired safety input, so a separate safety contactor is often not needed to reach the safety level stated in the specification.
• Several motor control modes – from simple volts per hertz for fans and pumps to sensorless and closed loop vector for conveyors, mixers and positioning duties, plus permanent magnet motor control.
• Modular design – the control module and power module separate, so configuration can be done while the power section is still being installed.
• USB programming – parameters can be loaded to the control module from a PC, which speeds up commissioning of several identical drives.
• Studio 5000 and Connected Components Workbench support – for integration with Rockwell control projects.

Typical applications for a 4 kW filtered drive

A 4 kW drive at 480 V class covers many workhorse loads: centrifugal pumps on water and wastewater skids, supply and extract fans, conveyors, agitators and packaging machine axes. The integral EMC filter is especially relevant in buildings and plants where drives share a supply with sensitive instrumentation, PLCs or communication equipment, as it reduces conducted emissions back into the mains without a separate filter enclosure.

Installation practice

• Mount the drive vertically with the clearances given in the user manual so cooling air flows freely through the heatsink.
• Use shielded motor cable, terminate the shield at both ends with suitable glands or clamps, and keep motor cables separate from control and network wiring.
• A filtered drive depends on a good, low-impedance ground connection; check the earthing of the cabinet and the PE conductor.
• Filtered drives are generally intended for grounded (TN/TT) supplies. On ungrounded or high-resistance grounded systems, follow the manual instructions for the filter ground jumper or select the unfiltered version.
• Wire Safe Torque Off according to the safety reference manual and validate the safety function as part of machine risk assessment.

Using the drive in Oman and GCC panels

Many control panels in Oman sit in plant rooms or outdoor kiosks where ambient temperatures are high for much of the year. An IP20 open-type drive must be installed in an enclosure, and the panel designer should calculate heat dissipation from the total watts loss in the specification table plus other components, then size ventilation or air conditioning accordingly. If the cabinet temperature will exceed the drive’s rated ambient, apply the derating curves from Rockwell documentation. Fine dust and humidity near the coast make sealed cabinets with filtered cooling the preferred option, and filter mats should be cleaned regularly.

Commissioning checklist

1. Enter motor nameplate data and run the autotune appropriate to the selected control mode.
2. Set acceleration and deceleration times to suit the load; for high-inertia loads consider the braking options described in the manual.
3. Configure the EtherNet/IP address and test communication with the controller.
4. Test the Safe Torque Off function and record the result.
5. Save a parameter backup for maintenance and spare drive replacement.

What to include in your RFQ

State the full catalog number 25B-D010N114, the quantity and whether any accessories are needed, such as a human interface module, a communication adapter, an IP30/NEMA 1 kit or line reactors. If you are replacing an installed drive, include a photo of the nameplate and indicate the application so we can check that the filtered version is appropriate for your supply system.
