Product Description:

The 12.F0.R11 belongs to the F0 Combivert Control Cabinets series produced by KEB. It is a three-phase inverter section intended to sit inside a coordinated control cabinet and supply regulated AC power to industrial motors in material-handling and process equipment. By combining power conversion, protective fusing, and auxiliary low-voltage supplies, the device forms the core of an automation cell that uses compact cabinet-mounted power electronics instead of separate wall-mounted drives. This arrangement helps keep the electrical layout centralized and supports orderly integration with other panel components.

The unit provides continuous apparent power of 6.6 kVA and a rated output current of 9.5 A, giving a clear basis for thermal planning and conductor selection. Heat generated at full electrical load is limited to 115 W, so enclosure airflow and heat-sink capacity can be sized without unnecessary cooling margin. Internal logic circuits are powered from a stabilized rail of +15 V, which helps separate control electronics from line disturbances. A 0.4 A Time-Lag control fuse disconnects this rail during faults, while a fast-acting 20 A intermediate fuse and an identical mains fuse protect the power section against overcurrent events. With three incoming line phases, the unit accepts balanced supply conductors up to 2.5 mm², and the terminal arrangement suits common industrial cabinet wiring practices.

The inverter can drive motors up to 4 kW and the housing has an IP20 protection class for installation inside closed panels. Operation is permitted at mounting heights up to 3000 m and in ambient humidity up to 95% non-condensing, which supports use in elevated or humid indoor locations when condensation is controlled. The assembly weighs 4 kg, which reduces mounting load on backplates and simplifies placement within compact cabinets. Supply and motor terminals both use conductor sizes up to 2.5 mm², keeping wiring uniform across the power connections. This consistent terminal sizing helps the panel layout remain straightforward when the inverter is installed beside contactors, filters, and other drive-related hardware.
