Product Description:

The 13.E4.T60-1001 electromagnetic compatibility filter is supplied by KEB within the Combiline EMC Filters series. Designed for installation ahead of a variable-frequency inverter, the device suppresses conducted and radiated interference so that servo networks, I/O modules, and fieldbuses can operate without disturbance. In plant automation cabinets, the filter mounts on the subpanel and works with the line reactor, grounding path, and overall noise-control layout. It is intended for medium-power drives that must meet industrial emission limits while keeping enclosure heat rise low.

The filter’s emission performance meets the EN 55011/B limit, meaning conducted noise measured on each line remains within Class B criteria for industrial use. Its input side tolerates up to 480 V (+5%), allowing connection to 400 V and 460 V three-phase networks with a 5 percent overvoltage margin. A continuous load of 16 A may flow through the choke and capacitive network without thermal derating, which matches typical drive ratings in the 7.5 kW range. The internal circuitry is arranged for 3 phases, and this topology helps maintain balanced impedance on each conductor and symmetrical leakage currents. Only 11.5 W of power is dissipated as heat during rated operation, so cabinet ventilation requirements remain modest.

The mains side uses a 3x AWG 10 supply terminal, providing ample conductor cross-section for the stated current while minimizing voltage drop. Connections to the inverter are routed through a narrower 3x AWG 14 terminal block that suits a typical drive pigtail harness. Signal integrity is maintained for motor leads up to 30 m, because the differential-mode attenuation is intended for that maximum cable length. The submount housing code is D, and it corresponds to a 1.3 kg chassis outline that allows direct fastening to DIN rails or backplates without extra brackets.
