CHENZHU REMIND YOU:

5 tips for your selection for a signal SPD

1)Maximum operating voltage Uc:

The maximum voltage of the signal circuit is less than Uc.

2)Nominal Operating Current IL

The maximum current of the circuit is less than this value.

3)Number of Wires:  2/3/4

Thermocouple is general 2-wires;

Thermal resistance is general 3-wires;


4) Other Main data:

Nominal Discharge Current In(8/20us): CHENZHU's signal SPD :C2:20kV/10kA/wire

Impulse Current Iimp(10/350us): CHENZHU's signal SPD  D1:2.5kA/wire


5) If is screwable SPD, please also pay attendtion to the male thread you need.
