Vector-capable MICROMASTER 440 control platform for demanding motor applications.
Product Overview
6SE6440-2AD25-5CA1 is a Siemens MICROMASTER 440 built-in drive for 380–480 V three-phase input, with an integrated Class A filter.
Siemens rates the unit at 5.5 kW constant torque and 7.5 kW square-law torque. The overload profile is 150% for 60 seconds and 200% for 3 seconds.
The product is cancelled and handled as a spare part. Parameter backup, motor data, field wiring and option records are essential before replacement.

Features
Integrated Class A filter in the stated 380–480 V execution.
Documented overload capability for short acceleration or process peaks.
Multiple digital, relay and analog interfaces for machine integration.
Applications
- Variable-speed control of compatible three-phase motors in machinery and process auxiliaries.
- Constant-torque duty up to the documented 5.5 kW rating.
- Square-law fan and pump duty up to the documented 7.5 kW rating.
- Lifecycle replacement where the original parameter set and option inventory are available.
Installation
- Export parameters and record motor nameplate data, command source, I/O assignments and fitted options.
- Isolate line and DC-link energy, then verify discharge under the Siemens procedure.
- Confirm frame, voltage class, filter, conductors, fusing, grounding and cooling clearances.
- Restore the validated parameter set and complete direction, interlock, speed and load tests.

FAQ
What should accompany a 6SE6440-2AD25-5CA1 enquiry?
Send the full nameplate, motor data, parameter backup, option list, control wiring, application duty and required quantity.
Can another 5.5 kW MICROMASTER replace 6SE6440-2AD25-5CA1 directly?
No. Voltage class, filter, frame, overload duty, I/O, options and parameter behavior must all be compared.
What lifecycle issue applies to 6SE6440-2AD25-5CA1?
Siemens marks it cancelled and directs users to spare-part service information, so availability and migration planning should be reviewed early.
What must be protected before removing 6SE6440-2AD25-5CA1?
Protect the parameter set, motor identification, terminal map, control source, safety chain and fitted operator or communication options.
What proves 6SE6440-2AD25-5CA1 is ready after exchange?
Confirm correct parameters, clean diagnostics, motor direction, current under load, interlocks and the approved process response.
