Product Description:
The 07.Z2.F04-1003 is a line reactor manufactured by KEB for the Z2 Three Phase Motor Chokes series. Installed between a variable-frequency drive and an AC motor, the choke adds series inductance to smooth the current supplied to the motor. This filtering limits harmonic distortion, reduces stress on motor insulation, and lessens conducted electromagnetic interference in automated production cells. The reactor is suitable for drive systems in which pulse-width-modulated output can otherwise create steep current edges and additional electrical stress.
The unit has an impedance voltage of 20%, indicating the percentage of nominal voltage dropped when the reactor carries its rated current. The wound core provides an inductance of 3.5 mH, supplying the reactance needed to filter the current waveform produced by the drive. The coils are insulated for a supply voltage of 400 VAC, making the reactor suitable for common European industrial power systems. Continuous current is limited to 2.6 A; operation within this limit keeps copper losses and core heating within the permitted thermal range. Three identical windings provide a three-phase configuration, allowing each motor phase to receive consistent current smoothing. The balanced winding arrangement also helps prevent unequal magnetic loading across the reactor core during normal motor operation.
The magnetic circuit remains effective at output frequencies up to 1600 Hz, allowing the reactor to operate with high-frequency inverter outputs. Its dielectric spacing supports a peak system voltage of 550 V, helping prevent insulation breakdown during transient overvoltage events. Core and winding losses total 18 W at rated load, and this heat is removed through natural convection because the unit does not include a temperature switch. The iron frame is drilled for hanging or vertical mounting, providing flexibility when arranging components on an enclosure back panel. Push-lock terminals simplify field wiring and eliminate the need to apply terminal torque with hand tools. With an installed mass of 3.5 kg, the reactor places a moderate mechanical load on the mounting surface while maintaining a compact installation profile.
