Product Description:

The 30.E4.T60-1001 is an EMC line filter manufactured by KEB as part of the Combiline EMC Filters series. Designed for three-phase drive systems, the unit is installed between the inverter and the mains to attenuate conducted high-frequency noise and limit emissions toward neighboring equipment. By integrating capacitive and inductive stages into a compact 135 mm × 390 mm × 390 mm chassis, the filter helps facilities comply with industrial electromagnetic compatibility limits and protects sensitive control electronics from back-propagated interference.

The filter is designed for C2 environments, meaning it targets industrial networks where some filtering is already present but further suppression is required before the public supply is reached. It handles a continuous phase-to-phase load of 650 A, allowing it to pair with large frequency converters without saturation. The permissible line potential is 400/480 VAC, so the same assembly can be used on common low-voltage grids found in Europe and North America. Internally, it uses delta-connected chokes arranged for a three-phase circuit, which keeps common-mode attenuation balanced across all conductors. Thermal dissipation under nominal load is 50 W, so enclosure ventilation must remove this heat to keep winding temperatures within safe limits.

The residual capacitive path to ground produces a leakage current of 60 mA, a value that must be considered when sizing ground-fault protection devices. For transient events, the filter withstands up to 528 V without dielectric breakdown, offering headroom above the rated mains envelope. The integrated output terminals support motor cable lengths up to 30 m, helping maintain the intended attenuation at the driven machine without additional ferrite cores. With a mass of 21.5 kg, the housing requires secure panel mounting, and four 12 mm diameter holes are provided to distribute the load and help prevent vibration from loosening the M10 power studs.
