3UG3511-1BQ50

The 3UG3511 relay monitors the phase sequence and the failure of one of the three phases. No settings are necessary during operation. If the phase sequence is correct and none of the three phases has failed, the output relay picks up after the delay time T1, and the LED lights up. In the event of a phase failure, the output relay releases after the delay time T2, and the LED goes out. If the phase sequence is incorrect when the voltage is switched on, the relay does not pick up.
