Yaskawa UZBA-B Line Reactor UZBAB

Description:

The Yaskawa UZBA-B is a line reactor used in industrial motor control and CNC systems to stabilize incoming power, reduce harmonics, and protect drives and motors, commonly installed in Yaskawa servo drive systems, CNC machines, and automation panels operating on 400–440V power, and purchased by maintenance teams, OEMs, and integrators for replacement of failed reactors and protection of sensitive electrical equipment.

Applications:

The Yaskawa UZBA-B reactor is used in industrial automation environments where power quality and equipment protection are critical. It is commonly deployed in CNC machines, variable frequency drives (VFDs), servo systems, and robotic equipment where it reduces voltage spikes, limits inrush current, and minimizes harmonic distortion to extend the lifespan of motors and drives.
