Product Description:

The 10.F0.220-3479 is an enclosed drive cabinet manufactured by KEB for the F0 Combivert Control Cabinets series. It is engineered as an all-in-one variable-frequency converter for enclosed industrial installations. The enclosed format places the drive hardware inside a cabinet structure suited for fixed installation in industrial control systems. It delivers regulated power from a three-phase supply to an AC motor, allowing machine speed and torque to be adjusted to match process demand in automation cells, conveyor sections, pump systems, and other equipment that requires controlled motor output.

This cabinet is designed for a three-phase input on 50/60 Hz networks and is optimized for grids centered on 400 V. Under rated conditions, it can supply up to 5.8 A of output current, corresponding to a continuous apparent power of 4.0 kVA. These ratings indicate the maximum continuous electrical load the inverter stage can handle without derating. The internal DC link is protected by an intermediate circuit fuse of 16 A, while the control electronics are isolated by a 0.4 A miniature fuse; upstream protection is limited to a 10 A mains fuse to coordinate fault clearing. A heat loss of 75 W at a 4 kHz switching frequency must be removed by the cabinet airflow so that semiconductor temperatures remain within safe limits.

The drive section can energize motors up to 2.2 kW, making it suitable for compact pumps, fans, and material-handling axes installed as high as 3000 m above sea level. Its enclosure carries an IP20 rating, so it requires installation inside a larger control panel and tolerates ambient moisture up to 95% relative humidity. A minimum side clearance of 50 mm and a top or bottom clearance of 100 mm maintain convective cooling paths. The stated clearances leave room for vertical airflow around the housing during normal operation. Field wiring must use conductors no smaller than 1.5 mm² to support current-carrying capacity and help limit voltage drop at the terminals.
