You will find that it has the Brown Boveri Electric Inc. branding, which I think to the part.
S.T.P.I. 240.182.AA Electric Relays 110/127V 60Hz
Installing the TRAKTRONIX relay was simple, and the markings were easy to read.
I like that this heavy duty relay seems built for real work, not just occasional hobby projects at home.
You can tell this heavy duty relay is made for tough spots, with thicker casing than many alternatives.
