Product Overview
Allen-Bradley 25A-D024N104 and 25A-D030N104 are Frame D PowerFlex 523 AC drives for 380…480 V three-phase motor systems. 25A-D024N104 provides 24 A at 15 HP, while 25A-D030N104 provides 30 A at 20 HP normal duty and 15 HP heavy duty.
The power section of 25A-D024N104 and 25A-D030N104 connects the three-phase supply, DC link, brake circuit and motor output through separate terminal groups. The 30 A rating changes the input-current and protective-device requirements even though both catalog numbers share the same Frame D enclosure.
Control wiring for 25A-D024N104 and 25A-D030N104 reaches the drive through digital inputs, analog reference or RS-485 DSI. When an output contactor is installed, its sequence must disable drive output before the motor circuit opens and keep output disabled until the contactor closes again.

Operating Characteristics
25A-D024N104 and 25A-D030N104 share Frame D but differ in current capacity and duty rating.
Thermal airflow
Vertical mounting keeps the Frame D inlet and outlet aligned with the intended cooling path.
Braking path
The included brake IGBT switches the connected dynamic-brake resistor circuit through BR+ and BR−.
Diagnostics and Protection
Protection of 25A-D024N104 and 25A-D030N104 combines branch-circuit devices, drive fault monitoring and controlled motor-circuit switching.
Input protection
The fuse or circuit breaker must match the complete catalog rating and its maximum input current.
Output switching
An interlock prevents the motor-side contactor from opening or closing while drive output is active.
Fault review
The keypad display presents the active fault code so the reported circuit or operating condition can be checked before reset.
Frequently Asked Questions
How do normal-duty ratings differ for 25A-D024N104 / 25A-D030N104?
25A-D024N104 is 11 kW (15 HP), while 25A-D030N104 is 15 kW (20 HP) at normal duty. The latter retains an 11 kW (15 HP) heavy-duty rating.
What airflow condition applies to 25A-D024N104 / 25A-D030N104?
Both Frame D drives need an unobstructed cooling path through the enclosure. Wiring ducts and adjacent equipment must not block the inlet or outlet.
Why is cabinet space reviewed for 25A-D024N104 / 25A-D030N104?
Clearance supports cooling and access to power and control wiring. Sharing Frame D does not permit the surrounding space to be omitted.
How should an output contactor be sequenced with 25A-D024N104 / 25A-D030N104?
Remove the output command before changing the contactor state. Restore the drive enable only after the motor circuit is fully reconnected.
Can the DC-bus terminals of 25A-D024N104 / 25A-D030N104 be treated as ordinary supply terminals?
No. They belong to the DC link and require the documented bus, precharge and discharge controls.
Why must conductor torque be verified on 25A-D024N104 / 25A-D030N104?
The Frame D terminal accepts specified conductor sizes and tightening torque. Recheck those values before energizing the installed drive.
