Yaskawa UZB91A 440V 61mH 50 60Hz Line Reactor

Description:

The Yaskawa UZBA91A is a line reactor used in industrial power and motor control systems to reduce harmonics, limit inrush current, and protect drives and motors, commonly installed in 440V CNC machines, servo drive systems, and automation panels, and purchased by maintenance teams, OEMs, and integrators for replacement of failed reactors and protection of sensitive electrical equipment.

Applications:

The Yaskawa UZBA91A line reactor is used in industrial automation environments where stable power quality and equipment protection are required. It is commonly deployed in CNC machines, variable frequency drives (VFDs), servo systems, and robotic equipment to reduce voltage spikes, minimize harmonic distortion, and extend the lifespan of connected motors and drives. These reactors are critical in maintaining consistent performance in high-load industrial systems.
