Mitsubishi FR-BAL-B-45K AC Reactor for FREQROL FR Series Inverters

The Mitsubishi FR-BAL-B-45K (FR-BAL-B-45K) is an AC reactor designed for use with Mitsubishi Electric FREQROL FR series variable frequency drives. Engineered to support 45 kW drive configurations, this reactor serves a vital function in power conditioning and electrical protection within industrial automation drive systems. It connects on the power supply side of compatible FREQROL inverters to suppress harmonic distortion, mitigate line noise, and significantly improve the input power factor. By dampening voltage spikes and managing current fluctuations from the incoming AC mains, the unit protects sensitive inverter components, DC bus capacitors, and power semiconductor modules from premature wear or damage. Built for dependable operation in heavy-duty environments, the FR-BAL-B-45K is commonly installed inside control cabinets for applications such as conveyor systems, industrial pumps, fans, compressors, and material handling machinery. Its integration ensures reliable motor speed regulation and enhanced system longevity across diverse manufacturing lines. The reactor facilitates compliant, efficient electrical operations while reducing electrical interference throughout the industrial plant network.
