Descrizione del prodotto

In many application with pumps, conveyors and fans efficient monitoring systems should help to detect failures and misfunctions in time, to avoid damage and long times of non-operation. Besides speed and frequency the monitoring of phase sequence is very important. The phase sequence relay with it's wide voltage range of 3AC380-690V detects a wrong phase sequence and signals via a galvanically separated relay contact the wrong rotation of a motor. By integrating the relay output into the enabling circuit of a plant, the unit disables the start of the plant in the case of wrong phase  sequence. Especially portable equipment can be protected in this way.
