Product description

The Siemens 6SE6440-2UD17-5AA0 is a MICROMASTER 440 frequency inverter designed for applications requiring variable speed control of AC motors. This unit operates on a 3-phase 380-480V AC supply and delivers a constant torque power of 0.75 kW. It features overload capabilities of 150% for 60 seconds and 200% for 3 seconds, with square-law torque power also at 0.75 kW. The compact dimensions are 173 x 73 x 149 mm (HxWxD), with an IP20 protection rating suitable for ambient temperatures from -10°C to +50°C. Importantly, this model does not include a built-in filter and operates without an AOP/BOP.

This drive is ideal for general-purpose machinery and automation tasks where precise motor speed regulation is needed, such as in conveyors, small pumps, fans, and other equipment where an external filter is not required or already integrated into the system. Its compact size and IP20 rating make it suitable for installation within control cabinets.

Frequently asked questions

When would I choose the Siemens 6SE6440-2UD17-5AA0 without a filter over a model with a filter?
