Product Description:
The 20.E6.T60-3050 electromagnetic interference filter is produced by KEB as part of the Combiline EMC Filters series. It is installed between a variable-frequency drive and the mains supply to suppress conducted noise that can interfere with sensors, PLCs, and communication links in industrial automation. Designed for side mounting in control cabinets that distribute up to 100 A per branch, it helps equipment meet the applicable emission limits on IT power networks. Its side-mount configuration also allows the filter to be positioned alongside compatible drive equipment without occupying the primary mounting area.
The filter supports a continuous load of 100 A at a rated system voltage of 400 V and a utility frequency of 50/60 Hz. A temporary overload of 150% for 60 seconds accommodates inrush conditions without saturating the LC network. Thermal losses remain at 54 W, so enclosure airflow or heat sinking must remove the generated heat to keep internal components within their operating limits. The LC topology provides wide-band attenuation while maintaining low insertion loss on IT mains. The line side accepts three conductors and a protective earth connection. Terminal screws require a tightening torque of 2.6 Nm, while the protective earth stud requires 14.2 Nm. When the drive switches at 4 kHz, the filter maintains its attenuation profile with motor cables up to 50 m long.
The unit fulfills electromagnetic compliance requirements for class C1, allowing installation in environments that also contain residential-grade electronics. Leakage current is limited to 2.02 mA, reducing the likelihood of nuisance ground-fault trips when multiple filters share one busbar. Its three-phase architecture matches standard inverters and soft starters used in industrial power systems. The filter has a mass of 4.95 kg, which must be considered when positioning and securing the side-mount brackets. Proper cable routing and balanced loading help prevent resonant peaks that could reduce attenuation performance. The protective earth connection must also be secured at the stated torque to provide a reliable grounding path during operation.
