Internal Product Review
The 13.F4.S3D-4000 is a KEB F4 Combivert frequency inverter with IP20 protection and 12 A nominal output current. Rated for 5.5 kW motor power with 10 A maximum braking current, the drive appears well suited for controlled industrial motion and dependable deceleration. Support for shielded motor line lengths up to 100 m is a particularly useful advantage for panel-based installations.

Product Description:
The 13.F4.S3D-4000 is an AC frequency inverter produced by KEB for the F4 Combivert Frequency Inverters series. The unit converts fixed-frequency mains power into a variable-voltage, variable-frequency output so three-phase induction or synchronous motors can be speed-controlled in automated machinery. Within an installation, the inverter sits between the utility supply and the motor, providing vector or V/Hz regulation, acceleration ramps, and managed braking behavior for conveyors, pumps, and other process equipment. This makes it suitable for machines that need repeatable motor response during startup, steady-speed operation, and controlled stopping.
In normal operation, the drive draws a nominal input current of 13.2 A and delivers a nominal output current of 12 A. That operating level corresponds to an apparent power of 8.3 kVA and supports a maximum rated motor power of 5.5 kW. The input stage should be protected by a 20 A mains fuse, and copper supply conductors with a cross-section of 2.5 mm² meet the thermal requirements of the terminals. An enclosure rating of IP20 means the unit is intended for installation inside a control cabinet, where contact protection is provided while ventilation space remains available for cooling. During rapid deceleration, the drive directs braking energy to an external braking path that is monitored by the control to help prevent resistor overload.
For short overload periods, the inverter tolerates 21.6 A before timeout protection intervenes, and an overcurrent trip occurs at 26.4 A. Dynamic braking uses an external resistor, and the design calls for a minimum resistance of 82 Ω; 110 Ω is listed as a typical selection for balancing stopping performance and heat dissipation. Shielded motor cables may be routed up to 100 m to help reduce conducted emissions in the installation. The housing measures 90 mm in width, 160 mm in depth, and 240 mm in height, which supports straightforward mounting in standard control enclosures and helps maintain orderly cable routing around adjacent components.
