Siemens 6SE6440-2AD24-0BA1 MICROMASTER 440 Frequency Converter

Description

The 6SE6440-2AD24-0BA1 is a MICROMASTER 440 frequency converter designed for high-performance industrial motor control. This unit features an integrated Class A filter to reduce electromagnetic interference and is engineered for versatile applications requiring precise speed and torque regulation.

Operating on a 3-phase supply of 380 V to 480 V (±10%) at 47–63 Hz, the converter delivers a nominal power rating of 4 kW. It is designed to handle demanding load profiles, supporting a constant torque overload capacity of 150% for 60 seconds and 200% for 3 seconds. With an IP20 protection rating, the 6SE6440-2AD24-0BA1 is optimized for installation within protected control cabinets, ensuring reliable operation in ambient temperatures ranging from -10 degC to +50 degC. This base model is configured without an AOP/BOP interface, focusing on high-efficiency drive core functionality.

Technical Specifications

Installation Guidelines

• Mounting: The unit must be mounted vertically on a flat, non-flammable surface inside a control cabinet.
• Cooling: Ensure sufficient clearance above and below the unit to allow for unimpeded airflow through the internal heat sink.
• Grounding: Secure a low-impedance connection to the central protective earth (PE) busbar to comply with EMC requirements.
• Cable Routing: Keep power supply cables separate from low-voltage signal and control wiring to prevent crosstalk and interference.
• Wiring: Use shielded power cables if necessary to maintain compliance with the integrated Class A filter specifications.
