Block switch – star – triangle – brake STS331

The device is intended for the smooth start of asynchronous electric motors and for the braking of a dynamic brake. Timings are set with trimmers on the front panel. It is also equipped with a safety relay, which enables a new start during the braking mode. Depending on the circuit diagram, the dynamic brake can also be switched on with a star. The selection of the mode is done manually – by jumping the jumper on the panel.
