3-phase voltage monitoring relays 5A, 260-410V AC, without neutral wire control, phase sequence control, Voltage

Three-phase voltage monitoring relay with undervoltage and overvoltage monitoring, time delay and automatic reset.

The main features of the new relays are:

- Monitoring of voltage exceeding the set value in at least one phase (HV), setting range 400V-510V GKT-03 and GKT-03F;

- Monitoring of voltage lower than the set value in at least one phase (LV), setting range: 260V-370V GKT-03 and GKT-03F;

- Setting of response time to voltage deviations from the set value (DT), range 0.1 s-20 s;

- Setting the relay contact return time after the voltage returns to the set values (RT).

- Automatic reclosing, range 0.1 s - 20 s;

- Phase sequence/phase presence monitoring in the network (GKM-02F and GKT-03F);

- Monitoring of supply voltage and relay activation if the supply voltage drops below 152 V (GKT-03 and GKT-03F);

- 3% hysteresis from the set voltage level to return the relay to working state;

- LED indicators for relay status and possible emergency situations;

- Control (NO+NC) with 5 amp dry contact switching;

- Compact size, DIN rail mounting.

Please note that these relays are designed only for disconnecting loads/devices/electrical goods from the power grid in case of overvoltage and neutral wire/phase loss. These devices do not regulate voltage!
