Product Description:

The 17.Z1.F04-1010 is a three-phase sine wave EMC filter manufactured by KEB for the Z1 Sine Wave EMC Filters series. It is installed between a variable-frequency drive and an AC motor to shape the inverter output into a near-sinusoidal waveform and to suppress conducted electromagnetic interference in automated production lines. By limiting dv/dt levels, the filter reduces motor insulation stress and minimizes bearing currents that can otherwise cause premature mechanical wear in continuous-duty applications. Its terminal blocks accommodate supply leads up to 16 mm², allowing direct connection to medium-current drives without extra distribution hardware.

Electrically, the core inductance of 0.28 mH smooths the steep switching edges generated by pulse-width-modulated drives operating up to the specified switching frequency of 2 kHz. When the filter is energized with a line-to-line voltage of 400 VAC, it can carry a continuous load current of 42 A without exceeding its thermal limits. Insulation clearances permit operation on systems where the DC bus may reach up to 550 V, giving headroom for regenerative events. The design passes three phases without a neutral, aligning with typical inverter output cabling in industrial control cabinets.

The unit has a base length of 219 mm and a base width of 100 mm, so it can be bolted inside narrow enclosures alongside drives. The laminated inductive core contains 1.9 kg of copper and brings total assembly mass to 6.6 kg, which aids heat dissipation during steady operation. At full load, the winding and core losses sum to 65 W, so cabinet ventilation must remove that heat to keep winding temperatures within limits. The housing height to the cable clamps is 215 mm, leaving clearance for routing shielded motor leads above the filter body.
