Internal Product Review
The 14.Z2.F04-1003 is a KEB Z2 three-phase motor choke rated for 16.5 A with 0.557 mH inductance. Low 31 mΩ resistance and 44 W power loss at 800 Hz make the unit a strong choice for efficient motor protection and cleaner drive output.

Product Description:
KEB manufactures the 14.Z2.F04-1003 as part of its Z2 Three Phase Motor Chokes series. This component is a three-phase line choke installed between the line supply and a variable frequency drive to increase source impedance, filter high-frequency switching currents, and reduce voltage peaks delivered to motor windings in industrial automation systems. By smoothing the current waveform and limiting harmonic content, the choke reduces stress on semiconductor devices and improves electromagnetic compatibility within control cabinets. Its three-phase design allows it to condition all phases within a single component rather than requiring separate reactors for each conductor.
An inductance of 0.557 mH provides the reactance needed to attenuate differential-mode disturbances at the operating frequency of 800 Hz used by KEB drive outputs. The choke has a rated current of 16.5 A, allowing it to operate on the line side of small and midsize inverters without saturation. Copper losses are limited by a winding resistance of 31 mΩ, which reduces the additional voltage drop across the reactor. Cable lugs sized for a conductor cross-section of 10 mm² / 8 AWG fit directly onto the RK 6-10/35 power terminals, simplifying cabinet wiring. These terminals provide secure attachment points for the phase conductors while supporting the stated wire size.
The choke dissipates 44 W when excited at its nominal frequency and 61 W at 1,600 Hz, so adequate convection or panel ventilation must be provided. A mass of 5.5 kg provides mechanical stability while keeping the unit manageable during installation. The protective earth stud accepts an M6 ring terminal and should be tightened to 4.5 Nm to maintain a low-impedance safety path. The unit measures 160 mm in height, 168 mm in width, and 280 mm in depth, allowing it to share DIN rail shelves or base plates with matching braking resistors and fuses without exceeding typical enclosure depths. These measurements also provide the clearance information needed to position the choke without obstructing nearby wiring channels or ventilation paths.
