Product Description:
The 09.Z2.F04-1003 is a three-phase motor choke manufactured by KEB for the Z2 Three Phase Motor Chokes series. It is installed between an inverter and an induction motor in automation panels. The choke raises line impedance to limit voltage slew rates and common-mode currents, helping protect motor insulation while reducing conducted electrical emissions.
This model carries a nominal current of 4.1 A and provides an inductance of 2.2 mH, allowing it to attenuate high-frequency components while passing the intended fundamental frequency with minimal voltage drop. Its copper windings have a direct-current resistance of 198 mΩ, which contributes to thermal dissipation during continuous operation. At a switching frequency of 800 Hz, total core and copper losses reach 32 W, so the cabinet must provide enough ventilation to remove the resulting heat and prevent saturation. An IP20 housing protects against accidental contact with live parts while allowing airflow around the choke. Push-Lock terminals accept conductors with a cross-sectional area of 6 mm², or 10 AWG, and enable tool-free wiring inside compact drive enclosures. The unit tolerates a continuous vibration amplitude of 0.3 mm and an operating acceleration of up to 10 m/s², supporting installation on machinery exposed to routine movement.
Losses increase to 44 W when the carrier frequency rises to 1600 Hz, so high-speed drive applications may require derating or forced cooling. In installations using elevated carrier frequencies, additional airflow helps keep the copper windings and laminated core within an acceptable temperature range. The choke remains functional at altitudes up to 2000 m without changes to its insulation class, even though reduced air density decreases the effectiveness of natural cooling. It withstands machinery shocks of up to 100 m/s² without displacement of the laminated core, which helps preserve stable electrical performance under sudden mechanical loads. The unit has a total mass of 3.9 kg, allowing it to be mounted near the inverter on a suitable DIN rail or mounting plate.
