Crouzet Phase, Voltage Monitoring Relay, 3 Phase, DPDT, 194 → 528 V, DIN Rail

The HWUA 3 phase network control relay monitors:- The correct sequence of phases L1, L2, L3,- Total phase failure,- Undervoltage and overvoltage from 2% to 20% of Under Voltage Relay,- Asymmetry rate from 5% to 15% of Under Voltage Relay,- Faults are signalled via LEDs, distinguishing the origin of the fault. If a fault persists for longer than the threshold crossing delay configured by the operator, both output relays open and LED R is extinguished.

Control of 3 phase networks: phase sequence, phase failure, asymmetry, under and overvoltage with independent settings
