It supports 3‑phase line voltage of 380–480 V ±10%, 47–63 Hz line frequency, and provides a 480 V rated output with a current rating of 4.10 A, making it suitable for moderate‑power, constant‑torque applications in industrial automation. The drive offers a wide speed range with an output frequency of 0–650 Hz (production limit 550 Hz) and a power factor around 0.95 with an efficiency of about 96%. Enclosed in an IP20 housing, it is intended for indoor use at ambient temperatures from -10 to +50 °C. Its compact form measures 173 x 73 x 149 mm (H x W x D), and it supports a robust overload capability of 150% of the output current for 60 seconds, followed by 100% for 240 seconds within a 300‑second cycle. The MICROMASTER 440 family offers control modes including Vector, FCC, and Linear – V\/F, enabling precise motor control and torque characteristics across varied loads. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268644688106,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6se6440-2ud21-5aa1-micromaster-vfd-380-480vac-1-5kw","provider":"GTG Hardware","version":"1.0","type":"link"}
