I have heard that aluminium clad resistors can damage a drive, is this true?

As we know a dynamic brake resistor is connected directly to the DC link on a drive, this is the main reservoir of power for the drive. You can imagine that shorting this connection can have catastrophic results for the input rectifier of a drive.

Some aluminium resistors are manufactured in such a way that in certain failure modes can cause them to short the DC terminals to the Earthed case, causing the drive fail. REO Aluminium resistors utilize a superior construction method to minimize the likelihood of this happening.
