Product Description:
The 20.Z1.F04-1010 is a three-phase sine wave electromagnetic compatibility filter produced by KEB for the Z1 Sine Wave EMC Filters series. Positioned between a pulse-width-modulated drive and the connected motor, the unit converts steep switching edges into a smooth sinusoidal waveform. This action minimizes conducted interference, protects motor insulation, and lowers bearing current in industrial automation systems that rely on variable-frequency drives. By suppressing differential-mode and common-mode noise, the filter also helps machines meet CE emission limits and permits longer motor cable runs without additional shielding.
The device is rated for continuous operation at 75 A with a phase-to-phase voltage of 400 V AC. It can tolerate overvoltage excursions up to 550 V without dielectric failure. The laminated core supplies 0.16 mH of inductance, which works with the downstream motor impedance to curb the rate of voltage change across the windings. Attenuation remains effective when the inverter switches at 2 kHz, covering the dominant harmonic spectrum produced by most sensorless vector drives. The filter is intended for three-phase networks operating at a fundamental frequency near 100 Hz.
Bolt-down terminals accept conductors up to 35 mm², allowing the filter to deliver its rated current without excessive resistive heating. Thermal losses are limited to 79 W, so ordinary panel ventilation usually provides adequate airflow. The assembly has a width of 243 mm and a height of 115 mm, leaving space for fuses, contactors, or line reactors in compact enclosures. Its windings contain 3.6 kg of copper, while the complete unit has a mass of 12 kg. The filter can be mounted beside compatible KEB drives, and its terminals accommodate standard cables of the supported conductor size. Proper spacing around the housing allows heat to dissipate while providing sufficient access for routing the three-phase conductors.
