Product Description:

The 15.E4.T60-4001 is an EMC power line filter manufactured by KEB and supplied within the Combiline EMC Filters series. The device is installed between the plant mains and the input of variable-frequency drives, servo inverters, or other switching power converters to suppress differential and common-mode noise that would otherwise propagate through the facility wiring and disrupt sensitive control electronics. By providing high-frequency attenuation on all conductors, the unit helps automation systems meet EMC directives and maintain reliable network communication inside cabinets without adding active components.

Its rated current is 30.0 A, indicating the maximum continuous line current the filter can process while keeping insertion loss within stated limits. The asymmetrical network accepts supply voltages up to 528 V AC, allowing connection to standard 400 V or 480 V three-phase grids with headroom for overvoltage conditions. For correct phase balancing, it is wired as AC 3PH+N, so line, line-to-line, and neutral interference paths are all attenuated. Compatibility with industrial mains at 50/60 Hz means the filter’s reactive components do not introduce unacceptable voltage drop at either common power frequency. This arrangement suits multi-drive cabinets that share one incoming mains connection.

The unit is assigned to the ambient class 3K3, which corresponds to indoor switchgear spaces where humidity, dust, and vibration remain within light-industrial limits. Under these conditions, the housing and impregnated windings tolerate ambient temperatures up to 45 °C before current derating is required. Mechanical integration is simplified because the unit is approved for drive enclosures whose supported frame size is ≤15, so it matches KEB inverters that share that mechanical code. The filter is intended for enclosed electrical cabinets used in typical indoor industrial settings.
