Zero Sequence Transformers from Controlled Magnetics

The standard features that you want

Weight and cost are both minimized by our efficient use of aluminum winding conductors. Your installation costs are kept to a minimum through our use of finger-safe terminations on units rated less than 150 amps. Transformers with higher current ratings have solid copper tab type terminals. The UL200C temperature rating of our insulation materials are economically utilized while maintaining adequate operating safety margins.

Optional features available when needed

There is no sense paying for features you don't need. That's why we've designed our standard ZST Series zero sequence transformers to include the features you must have, but to leave all others as options for you to choose only when you need them. You can specify thermal switches, enclosure types and many other options to your order when you need them.

Enclosures that meet your needs

While many transformer companies only offer enclosed transformers. because they use the cabinet walls as the transformer mounting brackets. You'll be pleased to know that we'll accommodate your needs for the enclosure and mounting method you want. Whether you need open core & coil construction or enclosures for Nema 1, Nema 12 or Nema 3R applications. We'll even provide Nema 12 potted construction for maximum protection and minimum audible noise.

Broad range of ratings available

Standard ratings range form 15 amps (phase current) up to 300 amps (phase current). Higher current ratings are no problem either – simply contact the factory any time you need a different rating. We'll be happy to quote the part that meets your exact needs. All zero sequence transformers manufactured by Controlled Magnetics are available in both low voltage and medium voltage ratings.
