Second, thesimpleselection table

1. Protection function.

Phase failure//wrong phase//over voltage//under voltage//three-phase voltage unbalance

1. Dynamic and static phase failure protection: If any phase of R, S, T is lost, the phase failure indicator will be on, and priority will be given to the relay.

2. Wrong and reverse phase protection: when R, S, T are out of phase, the reverse phase light will be on and the relay will act.

3. Over and under voltage protection: higher or lower than the voltage protection setting value, over and under voltage lights are on, and the relay is activated.

4. Three-phase voltage unbalance protection: the three-phase voltage unbalance rate is greater than 15%, the open-phase light is on, and priority is given to the relay.

5. Abnormal protection: When the input circuit itself has a phase failure or reverse phase fault, the protector will not act when it is powered on.

2. Action time

Protection item Operating time Operating conditions

Dynamic and static phase failure Less than 1S phase failure

Reverse phase Less than 0.1s reverse phase

Undervoltage Less than 8s, the operating voltage is lower than the set voltage value

Over voltage Less than 15s, the operating voltage is higher than the set voltage value

Three-phase voltage unbalance is less than 1.5s, voltage unbalance rate is greater than 15%

Abnormal protection There is a fault in the input power supply, and the protector will not act after power-on

Three, technical data

1. The three-phase power monitor is not affected by the current size of the line or load, the impact current, the unbalanced current and the nature of the load.

It can work for a long time with full performance and full climate. Power consumption is not more than 1.0W;

2. Anti-surge voltage 5000VAC, isolation 4000VAC;

3. Main circuit: rated voltage (below 3Φ690V AC, 50/60Hz)

4. Working temperature@maximum voltage, 50Hz: -20...+60°C, R is less than 95%

5. Auxiliary circuit:

Rated working current: 250VAC 2.5A, 110VDC 3A

Rated heating current: 5A
