Drop-in replacement CTs for breaker retrofit and life-extension projects — including obsolete and discontinued units other suppliers won't touch.
Breaker retrofit and switchgear life-extension projects live or die on parts availability. When a current transformer is obsolete, discontinued, or carries a year-long lead time, the whole job stalls.
Magnetics & Controls reverse-engineers and rebuilds retrofit CTs to match the original's fit, form, and function — built to print in the USA, so a single unavailable part no longer holds up an entire breaker.
We reverse-engineer CTs no longer made by the original manufacturer and rebuild them to match.
Matched to the original's dimensions, ratio, accuracy, and mounting so it drops straight in.
One unit or a batch — made in the USA on a timeline measured in weeks, not seasons.
We work from your drawing, datasheet, sample part, or an obsolete part number, and reverse-engineer to the original spec — typically at no charge, with any exception quoted up front before work begins.
If we've built your unit before and fabricate its components in-house, a same- or next-business-day quote is often possible. Retrofitting a fleet? We can also private-label the same CT across a production run.
Send us the part number, a drawing, or the unit itself. We'll tell you quickly whether we can reverse-engineer and rebuild it — and when you'll have it.
