Product Description:

The 16.E6.T60-1050 is an electromagnetic compatibility filter from KEB that belongs to the Combiline EMC Filters series. Installed between a three-phase drive and the mains, the unit attenuates conducted interference so that variable-frequency inverters meet industry emission limits and do not disturb adjacent control electronics. By providing a low-impedance path for high-frequency noise while maintaining the fundamental power frequency, the device improves system reliability in automated machinery and minimizes radiated disturbances on factory wiring.

The filter is designed for 400 V AC networks and carries a rated current of 43 A at that voltage; when connected to 480 V AC systems, its continuous current rating is 35 A. Internal terminals accept copper conductors rated for 75 °C, and the output side accommodates 10 mm² (AWG 8) cable for low resistive loss. Differential-mode and common-mode suppression introduce only 2.1 mA of leakage current to ground, remaining below typical residual-current device trip points. For first-resonance protection, the C1 section supports motor leads up to 50 m; beyond that length, an additional output choke is recommended. Upstream circuit protection may use IEC or UL fuses up to 50 A, matching the conductor thermal limits and short-circuit withstand capacity of the filter busbars.

Short overload events are handled with an admissible margin of 150% for 60 seconds, allowing motor acceleration without nuisance tripping. For longer cable runs, the C2 portion permits up to 100 m between the drive and motor while maintaining the required insertion loss. At nominal load, core and winding losses result in only 31 W of power dissipation, simplifying enclosure cooling calculations. The compact steel housing and impregnated choke assembly have a combined mass of 2.55 kg. This mass allows the filter to be mounted on suitable DIN rails or backplates beside drives and contactors.
