Siemens 6SE6440-2AC24-0CA1 MICROMASTER 440 Drive
A 200–240 V class MICROMASTER 440 rated 4.0 kW in constant-torque duty.
Product Overview
Siemens 6SE6440-2AC24-0CA1 is a filtered MICROMASTER 440 variable-frequency drive for three-phase 200–240 V supplies, regulating induction-motor speed and torque from its stored parameter set.
MICROMASTER 440 parameters define the motor, control method, ramps, limits and I/O behavior. A spare drive must be sized and parameterized, not merely wired.
This exact model is the 4.0 kW constant-torque unit in the 200–240 V three-phase class.
Motor nameplate, control source and parameter set remain installation-specific.

Motor-Control Functions
6SE6440-2AC24-0CA1 rectifies the three-phase input to an internal DC link and synthesizes a variable-frequency motor output under the selected MICROMASTER 440 control method.
Motor nameplate data, acceleration and deceleration ramps, current limits, digital and analog I/O assignments and command source are held in the drive parameter set.
Digital inputs, analog setpoints and communications can provide commands and references; the configured control source determines which path controls starting, stopping and speed demand.
Electrical Installation
For this Frame C drive, the compact operating instructions specify a 32 A fuse, 4–10 mm² input and output conductors and 2.25 Nm power-terminal tightening torque.
The 5.7 kg enclosure must retain the specified ventilation space and protective-earth connection before motor commissioning.
Protective earth, input fusing, conductor size and power-terminal torque must be completed before motor data identification and controlled commissioning are started.
6SE6440-2AC24-0CA1 FAQ
What is the rated output of 6SE6440-2AC24-0CA1?
Siemens lists 4.0 kW (5 hp) for constant-torque duty.
What input class does it use for 6SE6440-2AC24-0CA1?
It belongs to the 3 AC 200–240 V ±10% range.
Why is copying only frequency setpoints insufficient for 6SE6440-2AC24-0CA1?
Motor data, I/O assignments, command source, ramps, protections and control mode also affect operation.
Can a higher-power MICROMASTER 440 be installed without review for 6SE6440-2AC24-0CA1?
No. Supply, fusing, cable, motor and parameter compatibility must be engineered.
What electrical safety step comes first for 6SE6440-2AC24-0CA1?
Disconnect power, wait the specified discharge time and verify the DC link is safe before touching terminals.
Which load details must be matched when selecting 6SE6440-2AC24-0CA1?
Use the actual motor nameplate, duty, overload requirement, braking arrangement and control method, not only the 4 kW headline rating.
