Product Description:
The 24.Z2.F04-1003 is a three-phase motor choke produced by KEB and supplied within the Z2 Three Phase Motor Chokes series. Positioned between a variable-frequency drive and its motor, this inductor limits harmonic distortion, smooths current waveforms, and lowers dv/dt stress on winding insulation. By attenuating high-frequency components, it helps drive systems meet electromagnetic compatibility targets, reduces acoustic motor noise, and improves overall current quality in automated machinery. The unit is intended for upright installation inside control cabinets that operate on common 400 V and 480 V industrial mains.
The choke has a rated voltage of 400/480 V, allowing direct connection to low-voltage three-phase networks. Its windings handle a rated current of 180 A without core saturation, so drives operating at or below this current can benefit from the added impedance. The magnetic circuit provides 0.068 mH of inductance, which supplies the reactance needed to filter inverter switching edges. The copper bus bars have a resistance of only 2.4 mΩ, minimizing unnecessary conduction loss. At an inverter carrier frequency of 600 Hz, the choke dissipates 390 W of power. This heat dissipation must be considered when arranging airflow and cooling components in the surrounding enclosure.
The feed-through terminals accept lugs on conductors up to 70 mm², matching cable sizes commonly paired with 180 A circuits. The laminated steel core and copper windings bring the total mass to 32.8 kg, so the device must be fastened to a rigid backplate before wiring. The choke has a depth of 415 mm and a height of 170 mm. Its width is 365 mm, allowing it to occupy a vertical slot beside drives or contactors while leaving clearance for ventilation ducts and protective covers. Installers should account for the full enclosure depth as well as the space required to bend and terminate the connected conductors. The mounting surface must support the unit securely and maintain its upright position during operation.
