Mitsubishi FR-BAL-B-11-15K AC Reactor for FREQROL Inverters

The Mitsubishi FR-BAL-B-11-15K (FR-BAL-B-11-15K) is an AC reactor designed for use with Mitsubishi FREQROL series variable frequency drives. It is installed on the input power supply side of compatible inverter systems to improve overall power factor, suppress electrical line harmonics, and protect sensitive drive electronics from transient voltage spikes and line disturbances. Engineered for 200V class power distribution networks, the unit accommodates drive capacities ranging from 11 kW to 15 kW. By smoothing the input current waveform and attenuating harmonic noise, the reactor prevents nuisance tripping and extends the operating life of upstream power components and drive converters. Typical applications include manufacturing plants, automated material handling, pumping stations, ventilation systems, and industrial machinery where stable variable-frequency motor control is essential. This reactor provides robust and dependable performance in continuous industrial environments, ensuring power quality standards and operational reliability across demanding drive installations.
