Product Description:

KEB produces the 14.E6.T60-3050 as a line-mounted electromagnetic compatibility filter within the Combiline EMC Filters series. Installed between a frequency inverter and the utility supply, the unit attenuates conducted interference so machinery connected to a shared bus meets installation limits for sensitive industrial environments. By presenting low impedance to the desired 50/60 Hz energy while suppressing high-frequency noise, the filter protects upstream equipment and helps the drive system satisfy harmonized emission standards.

The filter is designed for a three-phase IT mains system and operates at a rated voltage of 400 V AC. It carries a rated current of 22 A and can tolerate an overload of 180% for 60 seconds, covering short production surges. During operation, leakage current to protective earth is limited to 1.92 mA. The EMC limit class is C1, so the component is suitable for installations in residential or light-industrial zones that impose restrictive emission limits. A degree of protection of IP20 indicates protection against finger contact with internal components but no protection against water. Overvoltage category III provides resistance to transients in fixed equipment. The design uses a spring-loaded power terminal that simplifies field wiring without torque-sensitive screw clamps.

Thermal loss is 13.5 W, allowing cabinet ventilation to be sized for modest heat dissipation. Continuous operation is permitted at a site altitude of up to 2000 m, while storage is permitted at altitudes up to 3000 m. The assembly weighs 1.22 kg, so it can be mounted on a DIN rail without substantial bracing. During wiring, the protective earth stud requires a tightening torque of 1.7 Nm to maintain a secure ground path. Overvoltage protection, grounding, and ventilation must be considered when the filter is installed in a control cabinet.
