It delivers a rated output of 1.1 kW with a nominal current around 4.9 A at 400 V and offers a constant‑torque rating alongside overload capacity of 150% for 60 seconds and 200% for 3 seconds, enabling short‑term surge handling. The drive accepts unfiltered 3‑phase input in the 380–480 VAC range and supports 47–63 Hz operation, with a compact enclosure measuring 173 x 73 x 149 mm (H x W x D), IP20 protection, and an ambient operating range from -10 to +50°C, without AOP\/BOP options. Typical uses include motor control in automation setups such as machine tools, pumps, and fans where reliable speed regulation and torque response improve process stability and energy efficiency.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268646719722,"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-6se6440-2ud21-1aa1-variable-frequency-drive","provider":"GTG Hardware","version":"1.0","type":"link"}
