The switch-on current limiter ED 1/16 enables the direct switching on of single-phase transformers, without triggering upstream safety devices as a result of the inrush current.The switch-on current limiter can be used for conventional transformers as well as for toroidal and strip-wound transformers.

• Protection class IP 00, IP 20
• No excessive inrush current of the transformer
• High transformer switch on frequency possible
• Use of transformers with low-loss sheet metals
