Mitsubishi FR-BAL-B-5,5K AC Reactor for FREQROL FR Series

The Mitsubishi FR-BAL-B-5,5K (FR-BAL-B-5,5K) is an AC reactor designed for use with Mitsubishi Electric FREQROL FR series variable frequency drives. Operating within the 200 V AC supply class and rated for 5.5 kW motor and inverter systems, this power factor improving reactor suppresses harmonic currents generated by the inverter, reduces power supply ripple, and protects the drive input stage against line surges and transient voltage spikes. The unit is typically connected on the power input side of compatible FREQROL FR inverters, contributing to improved energy efficiency, coordination with power distribution transformers, and enhanced operational stability across industrial automation environments. As a legacy component identified under discontinued production status, the FR-BAL-B-5,5K serves as an essential direct-fit replacement for maintaining existing drive cabinets, motor control centers, and continuous processing machinery. Typical applications include manufacturing lines, pumps, fans, compressors, conveyors, and automated machinery utilizing Mitsubishi FREQROL variable speed drive systems requiring power quality regulation and line reactance.
