Siemens 6SE6440-2UE17-5CA1 MICROMASTER 440 0.75 kW Inverter
High-voltage MICROMASTER 440 drive for 0.75 kW high-overload or 1.5 kW low-overload applications.
01Technical Summary
Siemens 6SE6440-2UE17-5CA1 is an unfiltered MICROMASTER 440 frequency converter for 500 to 600 V three-phase networks. It is rated for 0.75 kW high-overload duty or 1.5 kW low-overload duty and integrates the control I/O expected from the MM440 platform. The high-voltage supply class, low current range, motor insulation, external EMC design and precise parameter set distinguish it from visually similar 200 V and 400 V versions.

03Features
Key Functions
- Designed specifically for the 500 to 600 V three-phase supply class.
- Provides 0.75 kW high-overload and 1.5 kW low-overload ratings.
- Uses an unfiltered power-stage configuration for separately engineered EMC systems.
- Includes digital, relay and analog I/O plus PTC/KTY motor-temperature input.
- Supports MICROMASTER 440 motor-control and parameter functions.
- Uses an IP20 cabinet-mount enclosure supplied without an operator panel.
Identification
- Manufacturer: Siemens
- Model: 6SE6440-2UE17-5CA1
- Product Type: MICROMASTER 440 500-600 V variable-frequency drive without integrated filter
- Status: Cancelled product; spare part
04Compatibility
- Confirm that the installation provides a 500 to 600 V three-phase supply; lower-voltage MM440 units are not substitutes.
- Verify motor voltage, insulation system, full-load current, frequency and connection method.
- Engineer external filtering, grounding, shielding and motor-cable routing for the unfiltered article.
- Match AOP/BOP, communication module, braking equipment and all terminal functions.
- Confirm cabinet clearances and thermal conditions even at the comparatively low power rating.
- Use a verified parameter backup and review every limit, ramp and protection setting.
05Replacement
- Siemens identifies the article in the cancelled spare-part lifecycle.
- The general MICROMASTER 440 migration reference is Siemens SIOS 109746454.
- Any successor must support the 500 to 600 V supply class and the actual motor and control requirements.
- Record motor data, wiring, optional hardware and parameters before removal.
- After commissioning, test insulation-related requirements, motor current, direction, speed range, interlocks and process response.
06FAQ
Why is the supply class important for 6SE6440-2UE17-5CA1?
This version is designed for 500 to 600 V AC three-phase networks and cannot be selected as if it were a 200 V or 400 V drive.
What motor power is listed in high-overload operation?
The documented high-overload rating is 0.75 kW, or 1 hp.
What is the low-overload output-current value?
Siemens lists 2.7 A for low-overload duty; the high-overload value is 1.4 A.
Is an operator panel included with the converter?
No. The article is supplied without an AOP or BOP operator panel.
Which temperature-sensor input is supported?
The onboard motor-sensor input supports PTC or KTY temperature devices.
What should be retained before exchanging the unit?
Retain the complete parameter file, motor nameplate data, wiring schedule, options, supply information and protection settings.
