Product description
For three-phase drives, Siemens 6SE6440-2UD34-5FA1 provides the MICROMASTER-440 functions in an unfiltered 380–480-V version. The frequency converter is rated for a line frequency of 47–63 Hz and distinguishes between two load profiles: under High Overload, the rated power is 45 kW or 60 hp; under Low Overload, it is 55 kW or 75 hp. The corresponding input-current values are 87 A and 104 A. On the output side, up to 480 V is available at 90 A in High-Overload operation and 110 A in Low-Overload operation. The High-Overload profile permits 150 % output current for 60 seconds, followed by 100 % for 240 seconds within a 300-second cycle. In the Low-Overload profile, 140 % is provided for 3 seconds, 110 % for a further 57 seconds and then 100 % for 240 seconds. The pulse frequency is 4 kHz. For U/f control, the output-frequency range extends from 0 to 650 Hz; it is limited to 550 Hz in production. Together with the complete MLFB, these electrical parameters identify the specific version within the series. The IP20 enclosure is fan-cooled. Permissible temperatures are −10 to +40 °C in Low-Overload operation and −10 to +50 °C in High-Overload operation. The version is supplied without AOP or BOP; the operator panel and parameterization are therefore not part of the stated equipment features. The enclosure is 350 mm wide, 850 mm high and 320 mm deep. The net weight is 56 kg. The complete MLFB, filter version, load profile, connection data and dimensions are the decisive comparison features for unambiguous inventory identification.
The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ. Specifications
Unless expressly confirmed, technical information is provided to identify the device type. The complete manufacturer or type number is decisive.
