Three-phase voltage monitors without N monitoring monitor overvoltage and undervoltage between phases. The relay monitors under-voltage and over-voltage (separate settings) at its own supply voltage. An adjustable response time allows the output relay to be blocked in the event of short-term faults. If a voltage fault occurs, the relay opens after the delay set by the user has elapsed. If the supply voltage falls below 60% Un, the relay opens immediately without waiting for the delay. Fault status indication via red LED
1 changeover contact; setting range: undervoltage 75–95% of Un; overvoltage: 105–125% of Un, hysteresis: 2%, adjustable delay: 0.1–10 s;
