Product Description:
The 17.Z1.C04-1000 is a sine-wave electromagnetic compatibility filter produced by KEB as part of the Z1 Sine Wave EMC Filters series. Designed to sit between an inverter and motor terminals, the unit smooths the pulse-width-modulated output so that windings receive a nearly sinusoidal waveform. By limiting high-frequency components, it reduces conducted emissions, dampens cable-borne voltage spikes, and helps drive systems meet plant-level EMC limits in industrial automation. This output conditioning also helps reduce stress on motor insulation when long cable runs are used.
The filter is intended for three-phase mains grids at a nominal line voltage of 400 V; it accommodates standard industrial supplies running at 50/60 Hz. Under these conditions, the choke and capacitor network can pass a continuous phase current of 44.1 A without saturation, and it tolerates overloads up to 150% for 60 s/10 min so short production surges do not compromise attenuation performance. The housing carries an IP20 rating, which indicates finger-safe openings but no protection against liquids, making cabinet installation necessary. Connection lugs are sized for 16 mm² conductors, and an M8 protective-earth stud links the enclosure to the machine ground grid. These characteristics place the filter in duty class III service, where moderate environmental stress and repetitive cycling are expected.
At a motor load of 18.5 kW, the filter aligns with typical 22 kW drive panels, ensuring the voltage drop across the reactor does not exceed design limits. Internal winding resistance and core hysteresis contribute to a thermal dissipation of 270 W, which must be removed by switchgear airflow so the climatic category 3K3 temperature ceiling is not exceeded. By limiting total harmonic distortion on the motor side to 8%, the unit decreases acoustic noise and dielectric stress, which can help extend insulation life. A shipping weight of 47.1 kg reflects the laminated iron core mass required for low saturation flux density, and cabinet mounting rails must be able to sustain this load.
