Allen-Bradley Braking Resistors
Allen-Bradley is one of the leading drives providers across the world, with a very strong presence in North America. They currently rely on outside providers to supply external braking resistors; using their documentation we’ve developed comprehensive cross-reference lists.
If you’re a distributor, integrator, or end user of Allen-Bradley AC drives you will find this page useful for finding information on resistors, cross-references against Allen-Bradley part numbers, and getting a quote for a braking resistor.
All of our resistors are fully manufactured in Canada and are cULus listed. Whether you’re looking for a specific part number, or a customized product designed for your application, we can help.
We always provide the best prices, lead times, and quality.
Allen-Bradley has a two approaches to braking resistors. For some drives they provide a list of recommended resistors for specific model numbers, for which you can find a cross-reference list here.
The preferred and recommended approach by Allen-Bradley is to calculate the total braking power required, and reference the minimum resistance based on the drive you are using. We have transformed this into an interactive calculator on our website.
You can use this calculator to directly get a quote once completed by entering in your VFD model number.
