Allen-Bradley KDRA3LDR Drive Reactor Transformer

Description:

The Allen-Bradley KDRA3LDR Drive Reactor Transformer is used in three-phase variable frequency drive (VFD) systems to reduce harmonic distortion, suppress voltage transients, and protect motors and drive electronics from power line disturbances. Commonly installed in motor control centers, conveyor systems, pumps, compressors, HVAC equipment, and industrial automation machinery. Maintenance teams, OEMs, and system integrators use this drive reactor for equipment replacement, VFD retrofits, control panel upgrades, and power quality improvement.

Applications:

The Allen-Bradley KDRA3LDR drive reactor transformer is designed to improve the performance and reliability of AC drive systems by limiting inrush current, reducing electrical noise, and minimizing voltage spikes. It is commonly used in manufacturing facilities, water and wastewater treatment plants, packaging machinery, material handling equipment, HVAC systems, and process automation applications where improved power quality and extended equipment life are essential. The reactor is suitable for installation on the input side of AC drives to enhance power quality and extend the service life of motors and drive components.
