Product Description:
The 14.F0.R33-3429 belongs to the F0 Combivert Control Cabinets series from KEB. It is a cabinet-mounted frequency inverter that converts fixed three-phase mains power into variable-frequency output for industrial motors. In automated lines, the cabinet regulates speed and torque for conveyors, pumps, or positioning axes, and its integrated power stage, protective fuse links, and control terminals allow it to be mounted as a self-contained assembly instead of several discrete drive parts.
Electrical ratings show how the cabinet interfaces with plant power. It is built for a 400 V voltage class and accepts standard 50/60 Hz mains with a ±2 Hz tolerance across all three line phases. A protective fuse up to 25 A may be installed upstream to isolate the cabinet during faults. At nominal load, the inverter can deliver 16.5 A to the motor and supports a continuous mechanical output of 7.5 kW. Output frequency can be adjusted from zero up to 408 Hz, giving a wide speed range for fan or spindle duties. Short-term production peaks are covered by an overload capacity of 200 % for 30 s, so start-ups or rapid accelerations do not trip the drive. The terminals accept motor and mains conductors up to 4.0 mm².
Mechanical and thermal characteristics affect cabinet layout and airflow. The enclosure stands 340 mm high, 150 mm wide, and 251 mm deep, yet weighs only 5.0 kg, easing door mounting without heavy support brackets. Internally, switching devices can cycle up to 4 kHz, which lets the drive produce smooth current waveforms while keeping heat loss to 215 W that must be removed by cabinet airflow. When running at rated conditions, the inverter supplies 11 kVA to the motor terminals. Heat sinks are sized so airflow through the cabinet maintains component temperatures, while the rated wire cross-section keeps connection resistance low.
