ABB-48431-457

The ABB Braking Resistor, SKU ABB-48431-457, is engineered for effective energy dissipation in industrial motor control applications. This unit features a resistance of 1.35 OHMS and a substantial power rating of 121,500 WATTS (121.5 kW), making it suitable for high-demand braking scenarios. It is housed within an ED8 enclosure, providing a physical footprint of 30 inches wide, 18 inches deep, and 64 inches high. The total weight of the unit is 547 lbs. Manufactured by ABB - Low Voltage Drives, this braking resistor is designed to work with variable frequency drives (VFDs) to manage regenerative energy during motor deceleration. Its primary function is to convert excess electrical energy into heat, preventing overvoltage conditions and ensuring safe, controlled motor stops. The robust construction and significant power handling capability make it a reliable component for industrial machinery where precise speed and stopping control are critical. Originating from the US, this resistor is a key element in maintaining system stability and protecting VFDs from potential damage caused by energy feedback.
