ABB-43505

The ABB-43505 braking resistor from ABB – Low Voltage Drives is a high-power dissipation solution engineered for industrial motor braking applications. With a resistance of 1.39 ohms and a continuous power rating of 99,878 watts, it safely absorbs regenerative energy during deceleration, preventing overvoltage conditions in drive systems. The resistor is housed in a rugged ED7 enclosure, providing IP54 protection against dust and water ingress, suitable for harsh environments. Its compact footprint of 30 inches wide, 18 inches deep, and 56 inches high, combined with a weight of 442 pounds, ensures compatibility with standard industrial enclosures and mounting configurations. Designed for heavy-duty use in manufacturing, automation, and process control, the ABB-43505 extends the lifespan of motor drives by reducing thermal stress and voltage spikes during braking cycles. It is manufactured in the USA and carries the UNSPSC code 39122004 for procurement alignment.
