Product Description:

The 18.E4.T60-1001 is an electromagnetic compatibility (EMC) filter produced by KEB within the Combiline EMC Filters series. Installed between a variable-frequency inverter and the plant’s mains supply, the unit attenuates high-frequency noise so the drive system meets industrial emission limits. By targeting conducted disturbances on all three power lines, the filter helps nearby sensors, controls, and communication links operate without errors that originate from switching waveforms generated by pulse-width-modulated motor drives.

This model is sized for inverters identified by compatible inverter size 17, ensuring the copper, core geometry, and leakage inductance match the current demand of that drive frame. It withstands up to 3 x 480 V AC (+5%) on the line side, giving a voltage reserve that covers typical plant over-voltage tolerance. Connection is made on 3 input phases, so the filter processes all conductors symmetrically and preserves balanced loading of the supply transformer. Compliance with the radiated-emission benchmark EN 55011/B confirms that, when properly installed, the drive system can be certified for industrial environments where Class B limits apply. A compact depth of 66 mm minimizes enclosure footprint, allowing the filter to be mounted in the same cabinet row as contactors, circuit breakers, and line reactors without exceeding standard panel depths.

Mechanical integration is aided by a height of 445 mm and a width of 300 mm, dimensions that line up with the screw patterns of common control cabinets. The specified alongside/substructure mounting style lets installers place the filter either next to the inverter or directly beneath it to shorten cabling and reduce stray inductance. Nominal operation takes place on a 3 x 400 V AC supply, matching the most widely used European mains voltage. The unit handles conducted interference by design and, at 5.1 kg, it can be supported by standard DIN rails or base plates without additional reinforcement.
