Transformer SWITCHING relays

Our electronic relays allow for switching transformers and capacitors without any surges.

Using the soft starting procedure developed and patented by FSM Elektronik, one or several single-phase transformers can be switched during no-load operation or under load without starting current surge (inrush). Your advantage: transformers can be designed in a more cost-efficient and low-loss manner.

Where transformers have to be switched more frequently and where the waiting time between the switching procedures resulting from the use of starting current limiters cannot be tolerated, transformer relays are used. Furthermore, transformer relays are used in case of so-called half-wave failures of the mains voltage. If the same must not result in the fuses triggering, a transformer switching relay from FSM is the correct solution.
