Product Description:

The 16.E6.T60-3050 electromagnetic compatibility filter is produced by KEB within the Combiline EMC Filters series. Designed for installation on the supply side of frequency inverters and other switching drives, the device attenuates conducted emissions so that industrial machines can meet radio-interference limits on three-phase networks. Side-mounting hardware and an M4 protective earth stud allow the filter to be placed next to control cabinets without requiring changes to existing busbar layouts. This arrangement also provides a direct grounding point for safely conducting high-frequency interference away from connected equipment.

The filter supports a continuous line current of 43 A, enabling it to serve medium-power drives without saturation. Its maximum line-to-line voltage is 400 V, matching standard low-voltage distribution systems in production plants. Compliance with the C1 limit class permits use in the first environment where sensitive instrumentation may be present. The three-phase circuit routes symmetrical differential-mode and common-mode interference through a dual-stage network. Earth leakage is limited to 1.27 mA, allowing insulation monitoring devices on IT mains to operate without nuisance trips. A test frequency of 4000 Hz is used to assess insertion loss across the filter’s reactive elements and confirm attenuation performance at the applicable operating point.

Internal losses result in a steady power dissipation of 17.5 W, so cabinet ventilation must remove this heat to keep the dielectric materials within their temperature limits. During a 60-second transient, the filter withstands 180 % of its rated current, providing headroom during motor acceleration. Under worst-case conditions, the earth conductor carries 24.7 mA, which should be considered when selecting a residual-current protective device. The steel housing has a height of 305.5 mm and a width of 106 mm, allowing its required panel area to be established before installation. The unit weighs 1.79 kg, and its mounting screws require a tightening torque of 1.7 Nm. Adequate surrounding clearance should be maintained so that wiring can be routed without placing mechanical stress on the terminals.
