WRI WESTINGHOUSE SWITCHBOARD - NEED ANY CATALOG INFORMATION

[PE (always learning)]

Hey everyone,

I'm working on a power systems study for an existing data center that utilizes a Westinghouse WRI Switchboard with a 1200 amp main. This switchboard was installed in 1969 and I'm trying to determine what type of Westinghouse breaker would be used in this piece of equipment. If anyone has any brochures or information that could help me determine this, that would be greatly appreciated.

Also, this facility has two services and on the other side I've got a Westinghouse Pow-R-Line Switchboard with a 2500 amp main. This switchboard was installed in 1984 and I'm also trying to narrow dine what main circuit breaker this switchboard would use. Again, if anyone has any brochures or information on this particular piece of equipment that would be helpful as well.

I know these breakers could possibly be anything, but I'm trying to figure out what they could be without actually opening up the switchboards because it could be dangerous.

Any information is appreciated.

Best Regards

Thank you for info, I actually have taken a look at this one already, but any response is greatly appreciated!

Here's a picture of the switchboard I'm referring to, it actually has two transformer inputs for redundancy, with two 750 kva transformers and 480/277V secondary with 1200 amp mains.

Here's a picture of one of the 1200 amp mains in question. I don't have any catalog information, but if anyone can possibly tell what it is please let me know.

Your 1200A looks like a DB style breaker.
My 1989 Westinghouse catalog shows a Pow-R-Line switchboard using a PC style 2500A breaker.

Thank you sir! I appreciate the help and I am also amazed that you own a 1989 Westinghouse catalog. I'm glad you do though!

Westinghouse private labelled those to others. A lot of Westinghouse gear is that way.
