Product Description:

The 14.E5.T60-1001 is an electromagnetic compatibility line filter produced by KEB as part of its Combiline EMC Filters series. Installed between a variable-frequency drive and the line supply, the unit attenuates high-frequency interference so surrounding control equipment meets the limits specified for industrial environments. By targeting conducted emissions on three-phase power circuits, the filter helps keep motor-cable radiation within C1 [B] boundaries and prevents switching noise from feeding back onto the supply.

The filter is designed for a continuous load of 22 A and accepts supply levels up to 3 × 480 V AC (+10%), matching common 400 V and 460 V plant networks. It maintains predicted impedance across the line at a nominal frequency of 50/60 Hz ±2 and is wired for a symmetrical 3-phase + PE connection so phase balance is preserved. A low per-phase resistance of 0.010 Ω minimizes additional voltage drop and heat, while the C1 [B] emission class confirms suitability for equipment installed in residential or light-industrial areas where stricter limits apply. When the filter is positioned close to the drive input, the full 30 m maximum motor-lead allowance can be used without compromising conducted emission performance.

During operation, the filter dissipates 16 W, so natural convection is sufficient provided ambient temperature stays below 45 °C. Insulation integrity is demonstrated by a peak line-to-ground withstand of 2700 VDC for 2 s and a separate line-to-line test at 800 VDC for 2 s. Leakage current is 20 mA under nominal conditions and rises no higher than 115 mA when measured from phase to protective earth, which must be considered when selecting residual-current devices. The assembly weighs 1.5 kg and accepts screw terminals sized for 4 mm² (AWG 10) conductors, allowing quick panel integration adjacent to the inverter enclosure.
