Product description

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.
