Apr 9, 2014 #2 Hoxton Electrical Sep 5, 2006 434 Suggest that you call Alstom Grid in stafford UK +44 1785 223 251 They have details for all "legacy" products. Your relay is probably about 30 years old...... The "T" in CTM stands for "transistor" C = current M = Motor So it is a current operated motor protection relay, transistor technology. They should have an application guide, or at least a sales leaflet Upvote 0 Downvote
