Mitsubishi FR-ABR-0.4K Braking Resistor for FREQROL FR Inverters

The Mitsubishi FR-ABR-0.4K (FR-ABR-0.4K) is an external high-duty braking resistor designed for use with Mitsubishi Electric FREQROL FR series variable frequency drives. Engineered for inverter drive systems operating with motors rated up to 0.4 kW, this braking resistor unit provides reliable dissipation of regenerative electrical energy during rapid deceleration, stopping, and cyclic braking operations. By absorbing excess regenerative power that would otherwise feed back into the drive DC bus, the unit prevents inverter overvoltage trips and protects power semiconductor components from electrical stress. Constructed with a robust industrial housing optimized for thermal dissipation, the FR-ABR-0.4K resistor unit connects directly to the dedicated braking terminals of compatible FREQROL inverters. It is commonly deployed in demanding industrial drive applications requiring high stopping frequency or controlled deceleration of inertial loads, including conveyors, packaging machinery, sorting equipment, material handling lines, and automated assembly systems. This regenerative braking resistor ensures stable drive operation, shortens deceleration times, and maintains reliable system throughput across diverse industrial automation environments.
