Three phase circuits separation transformers application

The three phase circuits separation transformers have some characteristics in common with isolating transformers. They have two separate windings and require low-voltage. They are often used in informatics and electronics areas.

Product description

Thanks to performant, reliability components and our know-how, we master three phase circuits separation 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 transformer.

Delta/Wye connections with a Neutral.
