Allen-Bradley 1000-PF80R400W-NC-W-TA Power Resistor

The Allen-Bradley 1000-PF80R400W-NC-W-TA Power Resistor is a 400-watt braking resistor in the PF80R400W family, designed to dissipate regenerative energy in Rockwell Automation PowerFlex drive systems during braking and to protect the drive DC bus from voltage spikes. The PF80R400W designation denotes an 80-ohm resistance and a 400-watt rating, making it a common choice for braking networks in industrial drives. This Powerohm-branded resistor is used inside drive cabinets to convert electrical energy back into heat, supporting controlled deceleration and bus voltage management in automation systems powered by Allen-Bradley drives. Typical applications include motor drive braking circuits in industrial automation where reliable energy dissipation and compatibility with PowerFlex installations are required, including OEM equipment and retrofit scenarios. It is commonly installed as a replacement or maintenance part in PowerFlex drive systems and is compatible with standard braking configurations in cabinet-mounted drive setups.
