Product Overview
The Siemens MICROMASTER 440 variable frequency drive (VFD), model 6SE6440-2AD33-7EA1, is part of the industry-proven MICROMASTER 440 platform. It regulates three-phase AC motors using V/f control up to 480 V, providing adjustable constant and reduced torque output for industrial drives. Typical installations include pumping stations, conveyors, fans, and general machine tool applications requiring flexible motor speed control. The drive accepts 380-480 V AC input and delivers up to 45 kW continuous (60 hp), with overload handling and environmental design per industrial standards.
Best Suited For
- AC motor speed control in conveyors or fans
- Pump and compressor applications requiring adjustable torque
- Retrofitting of older MICROMASTER 440 systems
- Industrial machinery where compact IP20 drive is acceptable
