6SE64003TC075ED0

Overview

The Siemens 6SE64003TC075ED0 is a MICROMASTER 4 output reactor designed for 380-480V AC three-phase systems. It provides an inductance of 0.3 mH and supports a rated current of 90 A under Low Overload/Variable Torque conditions, or 75 A under High Overload/Constant Torque applications. The unit operates as a stand-alone component with a power loss of 0.277 kW and weighs approximately 27 kg.

Feature Summary

• Provides sinusoidal voltage shaping to protect motor insulation from inverter switching stresses
• Reduces common-mode voltage and dv/dt effects to minimize leakage currents
• Enables longer cable runs between the drive and the motor without signal degradation

Applications

• MICROMASTER 4 frequency converter systems
• Motor drives requiring extended cable lengths
• Applications demanding reduced electromagnetic interference

Procurement Notes

Verify the specific overload class (HO/CT vs LO/VT) required for your application, as the rated current differs significantly between these modes. Confirm that the 380-480V AC input range matches your network voltage. Ensure the mechanical mounting space accommodates the standalone chassis dimensions and weight.

Selection Notes

Select this component when using MICROMASTER 4 drives with cable lengths exceeding standard limits. Choose based on the continuous current requirement of the connected motor under the specific torque profile. Verify compatibility with the drive's switching frequency settings to ensure optimal filtering performance.

Part Context

This output reactor belongs to the Siemens MICROMASTER 4 accessory family. It serves as a passive filter component specifically engineered for variable frequency drives. Unlike line reactors, it is installed on the load side to condition the output waveform before it reaches the motor.

Replacement Considerations

No public confirmed substitute part numbers are available.
