Mitsubishi FR-BR-15K Braking Unit for FREQROL FR Inverters

The Mitsubishi FR-BR-15K (FR-BR-15K) is a dynamic braking unit designed for use with Mitsubishi Electric FREQROL FR series inverter systems. Operating as a critical dynamic braking component within FREQROL drive configurations, the FR-BR-15K absorbs and dissipates regenerative power produced when three-phase AC motors decelerate or stop under heavy inertia. By managing regenerative energy, this unit prevents DC bus overvoltage trips and ensures continuous, reliable operation of industrial drive setups. The Mitsubishi FR-BR-15K drive unit is engineered for demanding automation environments, including material handling, conveyors, packaging lines, and industrial processing machinery that require frequent start-stop cycles or rapid speed regulation. Built to industrial manufacturing standards, it provides seamless electrical and mechanical integration with compatible FREQROL inverters, ensuring enhanced system protection, operational safety, and extended equipment service life in factory automation facilities.
