Three-phase isolating transformers are intended to create electrical isolation between several circuits, often for safety reasons or to solve technical problems.

The three-phase isolating transformers are, for instance, widely used for operating rooms (refer to medical transformers) or machine power supplies : each room and each machine is equipped with its own isolating transformer to prevent any default from occurring and causing malfunctions in another room or machine. One of the main interests is to change the neutral regime mode in an IT installation (in case of use of computing equipment and/or sensitive electronic devices). Three-phase transformers are supplied in their standard configuration with the secondary neutral (earthed on request). Circé designs and manufactures three-phase isolating transformers according to your requirements while preserving the environment. We offer a low noise level while providing high efficiency. Our transformers are made of components guaranteeing performance and reliability whatever the quantity manufactured, unitary or in series. As with all our products, each transformer is individually tested and each batch is delivered with its control report.

Compliance

Our three-phase isolating transformers comply with the norm IEC 60076-11 / EC marking / EMC compatible / REACH / ROHS 2 / IEC 61558-2-1 ≤ 5 kVA.
