FACILITIES INSTRUCTIONS, STANDARDS, AND TECHNIQUES VOLUME 3-8 FIELD TEST PROCEDURE FOR PROTECTIVE RELAYS Internet Version of This Manual Created July 2000 FACILITIES ENGINEERING BRANCH DENVER OFFICE DENVER, COLORADO The Appearance of the Internet Version of This manual May Differ From the Original, but the Contents Do Not PThis is a comprehensive list of protective relays listed by part number/type/model that we buy, sell and repair. We provide nationwide repair services for obsolete electromechanical protective relays, switchboard meters and other obsolete electrical/electronic equipment utilized on electrical power systems. Before they started with model numbers such as CO-9, CO-11, etc to indicate curve shape, there was the CO. They have some old equipment manuals on this site, there are no CO type relays listed under Westinghouse, but most of them are listed under ABB. Good Luck. CO-9H1111N Westinghouse Overcurrent Relay Type: CO-9 60 Hz.

However I would suggest that you look in the Basler web site under protective relays (or call your local rep) and look at their solid state relay set up curves. I have found them (W) CO curves there. S1 cases. BE1-50/51B Overcurrent Relays may be tested without removing the relay from the case. Shorting contacts are provided for all current inputs when the connection plug or relay chassis is removed from the relay case.
