Overview

The ABB Braking Resistor (SKU: ABB-48431-456) is a high-power dynamic braking solution for industrial drive systems. With a resistance of 1.35 ohms and a power rating of 91,260 watts, it safely dissipates excess energy during deceleration, preventing voltage spikes that can damage drives. The ED7-rated enclosure provides IP54 protection against dust and water ingress, ensuring reliable operation in harsh environments like manufacturing plants, material handling systems, and heavy machinery. Measuring 30 inches wide, 18 inches deep, and 56 inches high, this resistor is designed for integration into existing control panels or standalone mounting. Weighing 442 pounds, it includes robust mounting provisions for secure installation. Compatible with ABB low-voltage drives, this resistor supports dynamic braking in applications requiring precise speed control and energy recovery. Its compact footprint and high power density make it ideal for retrofitting older systems or new installations where space and reliability are critical.
