Transformer switching relay TSRD

Make Inquiry

The TSRD is our standard product for switching on three-phase transformers of any design, for example for isolation transformers in special vehicles with rated currents of up to 50 A. For the operation of the TSRD, an external bypass contactor is required to bridge the internal actuators.

It also features soft-on, allowing three-phase transformers or three single-phase transformers together to be switched on at no-load or under load without an inrush surge. The inrush current surge is also avoided here and not just limited.
