3-phase current transformer-H1,ratio 200/5,50-400CYCLES
This was my Dad's. I had no idea what it was until I accidentally ran across one that looks just like this in a "GRAINGER" catelog (for $107.30)! The one I have says"RATIO 200/5 SPEC 3334 H1 2 1/2(in a circle) VA 50-400 CYCLES MODEL 33 USN CLASS GU INSTRUMENTS & ACCESSORIES CO.". The 6 terminals at the top are labeled "A1,A2,B1,B2,C1,C2". The "GRAINGER" catelog says "Use to monitor AC current. Connections are made using #8-32 threaded brass terminals."
