YASKAWA RH 0520W120 Braking Resistor Module AC drive 520W

Description:

The Yaskawa Electric RH 0520W120 resistor module is used in AC drive systems to dissipate regenerative energy during motor deceleration. Commonly installed in variable frequency drives, CNC machines, cranes, and high-inertia automation systems requiring controlled braking. Maintenance teams and system integrators use this part for repair, retrofit, and replacement of Yaskawa braking resistor modules.

Applications:

The RH 0520W120 resistor module is widely used in industrial automation environments such as conveyor systems, hoists, elevators, and CNC machinery where rapid deceleration generates excess energy. This braking resistor safely converts regenerative energy into heat, protecting drive components and improving stopping performance in motor control systems.
