By purchasing this item, you agree to the Terms & Conditions, ApterPower is not an authorized distributor for listed manufacturers or tradenames and therefore the manufacturer's warranty does not apply. All our products come with ApterPower's 1-year warranty.
The ordered configuration is a MICROMASTER 440 drive for 380-480 V three-phase supplies, rated 11 kW constant torque and 15 kW variable torque.
In service, the hardware controls induction-motor speed and torque using parameterized converter functions and programmable I/O.
Correct selection depends on line voltage, motor data, load duty, frame size, braking needs, EMC components, option boards and parameter backup.
The current order is identified by the complete 6SE6440-2UD31-1CA1 marking and its documented relationship to MICROMASTER 440.
The hardware is used in conveyors, pumps, fans, material handling and general industrial motor control, where it controls induction-motor speed and torque using parameterized converter functions and programmable I/O.
Installation planning must account for line voltage, motor data, load duty, frame size, braking needs, EMC components, option boards and parameter backup. isolate and discharge the DC link before work; the replacement must be commissioned from verified motor and application data
Availability is confirmed against the complete model, revision, quantity and delivery destination.
Verified resources for Siemens 6SE6440-2UD31-1CA1:
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Supports conveyors, pumps, fans, material handling and general industrial motor control without changing the documented host architecture.
Serves maintenance teams restoring the original MICROMASTER 440 signal, control or power path.
Fits modernization planning when the existing installation must remain operational while a long-term migration is evaluated.
The unit's performance is defined by how reliably it controls induction-motor speed and torque using parameterized converter functions.
Stable performance operation in MICROMASTER motor control requires the source, load and connected interfaces to remain inside the published design.
Application results should be verified with the host diagnostics and the real conveyors, pumps, fans.
Use host-system status, alarms and service indications to verify the ac variable frequency drive after installation.
Trend or diagnostic records from the original unit provide the baseline for detecting a channel, network or configuration mismatch.
A successful replacement requires both a clear hardware status and a functional test of the assigned conveyors.
Configuration data belongs to the installed MICROMASTER 440 project and should be backed up before hardware removal.
Revision, firmware, address and option settings must be reviewed together with the complete order number.
Commissioning should load only a validated project or parameter set and then confirm the intended operating state.
Description
Siemens 6SE6440-2UD31-1CA1 defines a MICROMASTER 440 drive for 380-480 V three-phase supplies, rated 11 kW constant torque and 15 kW variable torque. The complete order identity ties this hardware to the MICROMASTER 440 platform rather than to a visually similar device.
Within the installed architecture, it controls induction-motor speed and torque using parameterized converter functions and programmable I/O. Its principal connection boundary is three-phase mains, motor output, control terminals and optional communication/operator modules, making the unit suitable for conveyors, pumps, fans, material handling and general industrial motor control.
For a controlled replacement, confirm line voltage, motor data, load duty, frame size, braking needs, EMC components, option boards and parameter backup. Isolate and discharge the DC link before work; the replacement must be commissioned from verified motor and application data

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What ac variable frequency drive confirms the exact 6SE6440-2UD31-1CA1 configuration?
Use the complete model and the defining configuration: a MICROMASTER 440 drive for 380-480 V three-phase supplies, rated 11 kW constant torque and 15 kW variable torque. Include every suffix and secondary assembly number shown on the nameplate.
Which installed-system evidence is decisive for matching 6SE6440-2UD31-1CA1 as a ac variable frequency drive?
Confirm line voltage, motor data, load duty, frame size, braking needs, EMC components, option boards and parameter backup. The match must be made to the installed MICROMASTER 440 records, not only to appearance.
Where does 6SE6440-2UD31-1CA1 perform its documented ac variable frequency drive duty?
The documented application is conveyors, pumps, fans, material handling and general industrial motor control. In service, it controls induction-motor speed and torque using parameterized converter functions and programmable I/O.
How should a buyer establish the present supply route for 6SE6440-2UD31-1CA1?
The OEM lifecycle is recorded as Discontinued / Obsolete by OEM. Apter Power confirms actual condition, available quantity, lead time and destination before issuing a dated offer.
What field condition can prevent a like-for-like 6SE6440-2UD31-1CA1 replacement?
Isolate and discharge the DC link before work; the replacement must be commissioned from verified motor and application data Compare the proposed unit with other MICROMASTER 440 frame C variants only through official service documentation.
Which records should accompany a 6SE6440-2UD31-1CA1 datasheet and quotation request?
Send clear nameplate photos, host model, revision, wiring or slot reference, required quantity, destination and requested delivery date so the exact datasheet and quotation can be matched.
