Siemens 6SE6440-2UC17-5AA1 Variable Frequency Drive

Siemens 6SE6440-2UC17-5AA1 Micromaster 440 variable frequency drive delivers 0.75 kW (1 hp) of output from a 200–240 V AC supply with a 47–63 Hz operating range. This “without filter” variant is built for compact installation and comes in an IP20 enclosure measuring 173 x 73 x 149 mm (H x W x D), with ambient operating temperatures from -10 to +50 C and no AOP/BOP options. The drive provides overload resilience of 150% for 60 seconds and 200% for 3 seconds, and it uses square‑law torque characteristics to specify its rated torque of 0.75 kW. It is designed for steady, reliable speed control of constant‑torque loads and is commonly used in small conveyors, pumps, fans, and light machine tools where precise motor control is required. The model is part of the Micromaster 440 family, optimized for compact automation tasks and easy integration with standard control wiring for 200–240 V systems.
