Product Description

The Allen-Bradley 41391-261-52 is a legacy SMC-Flex power-pole assembly intended for maintenance of compatible smart motor controller installations. It forms part of the controller's power-switching path, where the SMC-Flex system manages the voltage applied to an AC motor during starting and stopping.

For maintenance teams, a correctly matched power pole helps restore the original controller structure without replacing the complete soft starter. Because 41391-261-52 is a legacy repair number, selection must be checked against the installed controller catalog number, frame, line voltage and current rating, Series/Revision, wiring arrangement and the manufacturer's replacement guidance.

Before ordering, compare the existing assembly label and connector arrangement with the required spare. Installation should be performed only on a fully isolated system by qualified personnel, by inspection, parameter verification and controlled commissioning.

Product Features & Functions

SCR-Controlled Starting and Stopping 41391-261-52 forms part of the SMC-Flex SCR-controlled power path, which regulates motor voltage during programmed starting and stopping.
Integrated Bypass Operation After the motor reaches operating speed, the SMC-Flex controller transfers the power path to its integrated bypass for normal running.
Three-Phase Power-Path Role The assembly occupies one power-pole position in the controller's three-phase structure and electronically switches its assigned motor phase.

Technical Notes

Electrical Safety: Disconnect and verify all line and control power before servicing 41391-261-52. SMC-Flex output terminals can be energized whenever line voltage is present, even when the motor is stopped.

FAQ

Which markings should a receiving inspector compare on 41391-261-52?Use the physical label as the acceptance reference: the part number must read 41391-261-52, with a 3:1 current-ratio marking and YELLOW / BLUE lead identification. Stop the inspection if any of these identifiers differ from the ordered unit.
Can 41391-261-52 be selected only by matching the appearance of another SMC-Flex power pole?No. Rockwell Automation maintains power-pole replacement information by part number and controller configuration, so a similar housing is not proof of interchangeability. Use the installed controller catalog number, Series/Revision and electrical rating when selecting the service part.
Which main-circuit terminals matter when checking wiring after 41391-261-52 is installed?For a line-connected motor, incoming three-phase power terminates at L1/1, L2/3 and L3/5, while the motor connects at T1/2, T2/4 and T3/6. Match the serviced pole to its installed phase position before energizing the controller.
Why must line power be isolated before servicing 41391-261-52 when the motor is stopped?A stopped motor does not prove that the SMC-Flex output is de-energized. Rockwell Automation states that voltage can remain present at the output terminals whenever line voltage is applied, so line and control power must be isolated and absence of voltage verified before service.
What operating transition should technicians expect after 41391-261-52 is returned to service?The SMC-Flex uses solid-state power control during starting and stopping, then its integrated mechanical run contactors carry each motor phase during normal operation to reduce heat. If the controller does not reach normal run, use its fault indication and phase-current readings before attempting repeated starts.
What should a buyer include in an RFQ for 41391-261-52?Send the existing power-pole label, the complete SMC-Flex controller catalog number, Series/Revision, line voltage and current rating, plus clear photos of the bus-bar and lead connections. This information lets the supplier screen the requested service part before the planned shutdown.
