Three phase circuits separation transformers application

The three phase isolating transformers are used to create electrical insulation protection between several circuits. They are often placed in operating rooms or electronical devices.

Product description

Thanks to performant, reliability components and our know-how, we master three phase isolating transformers according to your specific requirements.

Each product is individually controlled and each batch is delivered with its control report.

Coupling / Connection

According to the transformer power, using screw, transformer terminal block with self-rising clamping plates or linergy passthrough terminal block to connect the transformers and using clamping range above 200 kVA.

Delta/Wye connections with a Neutral.
