Product Description:

The 10.M4.C2D-3420 belongs to the F4 Combivert Frequency Inverters series manufactured by KEB. As a variable-speed AC drive, it converts fixed-frequency three-phase line power into a controllable output for induction motors used in conveyors, pumps, and general automation. Within the series, this model is intended for machinery that requires moderate power while also requiring sealed construction for washdown or outdoor installation. That enclosure style allows the drive to be mounted close to the machine in locations where dust or water spray may be present. It is suited to installations that need drive control without placing the inverter in a separate indoor cabinet.

The inverter is designed for a 400 V supply network and delivers a continuous motor current of 5.8 A, which corresponds to an output capability of 4 kVA. This current level suits small to mid-sized motor loads in standard industrial duty. For short-duration acceleration or load peaks, it can supply 10.4 A, and it supports motors rated up to 2.2 kW. Heat generated in the IGBT stage is removed through an aluminum heat sink rated for a maximum surface temperature of 70 °C. The internal switching devices operate at 4 kHz to limit audible noise without excessive switching losses. During normal operation, the unit draws a nominal input current of 6.4 A from a three-phase feeder, dissipates 80 W as thermal loss, and uses an electronic trip that activates at 12.7 A to protect the inverter and motor windings.

Installation parameters include a maximum line fuse of 10 A and connection terminals sized for conductors up to 1.5 mm². Terminal capacity should be matched to the selected supply and motor leads to maintain secure wiring. The housing is sealed to IP65, preventing dust ingress and protecting against low-pressure water jets, so external cabinets are unnecessary in most factory settings. A shielded motor cable may be run up to 5 m to maintain EMC compliance. The controller stands 210.5 mm high, which helps it fit compact enclosures and tight machine-side mounting spaces.
