6SE6440-2UE34-5FA1 SIEMENS

The MICROMASTER 440 6SE6440-2UE34-5FA1 is a high-performance, filterless frequency inverter designed for three-phase AC power systems operating between 500 and 600V (+10/-10%) at 47-63 Hz. It is engineered to deliver a constant torque power of 45 kW, with an overload capacity of 150% for 60 seconds and 200% for 3 seconds, making it suitable for demanding applications. For squared torque loads, it provides a power output of 55 kW. The inverter's dimensions are 850 mm in height, 350 mm in width, and 320 mm in depth. It features an IP20 protection rating, ensuring protection against solid objects. It is designed to operate in ambient temperatures ranging from -10 to +50 degrees Celsius. This model does not include an Advanced Operator Panel (AOP) or Basic Operator Panel (BOP). It is ideal for controlling the speed of three-phase AC motors in a variety of industrial applications. Its robust design and overload capabilities ensure reliable performance in challenging environments. The absence of a filter makes it suitable for applications where harmonic distortion is not a major concern or is addressed by external filtering solutions.
