Product Description:
The 20.F4.T60-1029 is an EMI filter accessory produced by KEB for the F4 Combivert Frequency Inverters series. It is installed between the mains supply and the drive to suppress conducted high-frequency noise and help the inverter comply with electromagnetic compatibility limits in industrial automation. By limiting the propagation of switching disturbances back into the plant’s power distribution system, the filter protects adjacent equipment and allows the drive to share panels with sensitive control electronics. Its compact housing matches the mechanical outline of the associated F4 inverter frame.
The accessory is an EMI (CE) filter that functions as an HF filter, attenuating high-frequency components produced by inverter switching. It is designed for supplies operating at 50/60 Hz and accepts a balanced three-line input from a three-phase system. The nominal line-to-line voltage may rise to 3 × 460 VAC with a +10% tolerance, aligning the filter with drives in the same voltage class. The continuous load capacity reaches 110 A, so the filter can be paired with larger F4 inverters without excessive temperature rise. Its internal components support this current at an ambient temperature of 45 °C while maintaining low insertion loss and remaining within thermal limits. The filter connects to the mains side of the inverter and directs unwanted high-frequency current away from the plant supply network.
On the supply side, the PE, L1, L2, and L3 terminals provide the incoming connections, while the downstream inverter connects to dedicated conductors marked PE, L1′, L2′, L3′, and N′. Separating the supply and inverter connections helps reduce crosstalk between the two wiring sections. The unit belongs to the 460 V class, so its creepage distances are suitable for typical North American motor circuits. Its R-coded mounting housing allows the filter to be bolted to the drive chassis or a common backplate without additional brackets. Operation is permitted over a temperature range of -25 to +85 °C, allowing cold starts in unheated equipment rooms and continued service in warm control cabinets. Adequate panel spacing and ventilation help prevent surrounding equipment from raising the filter temperature beyond this operating range.
