Z2 Three Phase Motor Chokes

Engineered specifically to safeguard motors from the adverse effects of variable frequency drives, the KEB Z2 Three Phase Motor Choke Series provides controlled impedance to mitigate PWM voltage spikes that shorten motor lifespan. By reducing dV/dt stress, these chokes enhance insulation integrity and prevent premature failures. Offering both 3% and 5% impedance options, the Z2 series is configurable for different voltage classes up to 460V, providing tailored protection across diverse industrial applications and distances. Robust construction withstands overload conditions up to 200% of full load amperage for short periods, ensuring reliable performance despite demand spikes. Global safety certifications validate stringent standards compliance. From injection molding machines to conveyors, the KEB phase chokes protect long motor cable runs from reflected wave damage, promoting system longevity and continuity in VFD-driven automation. By preserving motor health, the series reduces downtime and replacement costs while also extending equipment service life through proven technological innovation.
