Single phase control and signalling  transformer application

Single phase control and signalling transformers are created in order to supply control and signalling equipment housed inside an enclosure (e.g. contractors, automation systems…)

The transformers are available without or with housings ( DIN Rail mounting, IP23, IP33, IP55).

Product description

Circé designs and produces single phase circuit separation including renforced isolation between input and output windings.

Thanks to performant, reliability components and our know-how, we master single phase circuit separation 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.
