Typical applications
3 phase isolating transformer according to IEC/EN61558-2-4 for general applications, e.g. for providing electrical (galvanic) isolation according to VDE0700/EN60335 regulations or network supply transformer (e.g. TN network system).
Specifications
3 phase isolating transformer according to EN61558-2-4. protection class I ready. Due to innovative vacuum impregnation in polyester varnish, the noise level is extraordinary low. Screw terminals are contact proof according to VBG4.
Standard switching matrix: Yyn0 (max. typical star load of phase current: approx. 10%). Switching matrix: Please note the distinction between different voltages (e.g. phase voltage, line voltage). For further information, don´t hesitate to contact us!
Any user-defined mounting position is possible.

3 Phase Isolating Transformers Circuits and Circuit Designs
3 phase isolation transformers offer various possibilities to connect PRIMARY and SECUNDARY winding.
Each design allows specific transformer characteristics. See the following table for preferred circuit designs.
- Neutral wire “N“ or “n”. Percentage of neutral wire current allways refers to nominal current of phase conductor.
- Please mind:
- Secundary star circuit allows load on neutral wire.
- Parallel connection of transformers must comply to following criteria:
- Nominal voltage and rated frequency
- Circuit design
- Short circuit voltages
- Ratio of rated loads should not extend 3:1
