Product Description:

The 10.F4.C3D-4M00 is a frequency inverter produced by KEB within the F4 Combivert Frequency Inverters series. Designed for cabinet installation, the unit uses the compact D housing and weighs 2 kg, making it easy to integrate into small control enclosures where mounting space is limited. By converting fixed-frequency three-phase mains power into a variable output, it regulates asynchronous motor speed and torque in automated conveyors, pumps, and machine tools. A built-in filter and braking transistor simplify wiring and help protect both the drive and the connected motor during dynamic cycles.

During continuous operation, the inverter draws a nominal input current of 6.4 A from the supply and delivers an output nominal power of 4 kVA to the motor. At 400 V, this corresponds to a maximum rated motor power of 2.2 kW, while the output nominal current remains at 5.8 A for steady load conditions during normal operation. An overcurrent trip threshold of 12.7 A shuts the drive down before device or winding damage occurs, and a user-selectable 10 A mains fuse provides upstream protection. All terminations accept 1.5 mm² line conductors, and the IP20 enclosure prevents accidental contact with live parts but requires mounting in a clean control panel.

For short overloads, the inverter can supply up to 10.4 A for a few seconds, and its braking transistor handles a peak regenerative current of 5 A when decelerating high-inertia loads. To dissipate this energy safely, the application must use a braking resistor no smaller than 160 Ω, and KEB recommends a typical value of 270 Ω for balanced thermal loading. The control electronics remain stable in humid production areas, tolerating ambient relative humidity up to 95 % without condensation. These values help size braking components and support stable deceleration behavior in applications with regenerative loads.
