Product Description:

The 10.F0.R11-4009 belongs to the F0 Combivert Control Cabinets series produced by KEB. It is a preassembled cabinet section that accommodates power electronics for speed-controlled induction or synchronous motors used in automated machinery. Within an installation, the unit forms the interface between the plant’s mains supply and the connected drive, providing regulated output power and coordinated low-level reference signals to the drive controller.

The cabinet is designed for a nominal supply of 400 V and accepts a three-phase input, giving it direct compatibility with standard industrial grids. Under rated conditions, it can deliver 4.0 kVA of apparent power and a continuous line current of 5.8 A to the inverter section. Thermal losses generated during conversion reach 75 W, so forced-air ventilation is typically required inside the machine enclosure. A 10 A mains fuse provides upstream protection, while the 16 A intermediate fuse limits DC-link fault energy and the 0.4 A control fuse protects low-voltage logic circuits. Power cables are terminated on spring or screw clamps sized for a conductor cross section of 1.5 mm². The same conductor size supports internal wiring for reference and auxiliary circuits. Reference commands are supplied as +10 V at 6 mA, and an auxiliary +15 V rail rated at 30 mA is available for external sensors.

The drive section can supply motors up to 2.2 kW without derating, matching small pumps, fans, or conveyor axes in compact machines. An enclosure classification of IP20 means the cabinet must be installed inside a control desk or equipment rack to prevent accidental contact with live parts. The cabinet frame weighs 4 kg, which reduces the load placed on the supporting panel or gantry. Internal wiring uses a single conductor path that keeps resistive losses low. Its routing also helps reference and auxiliary currents remain within their required tolerance ranges when placed near higher-power cables.
